	abstract = {During investigation of the homogeneous H-2-hydrogenation of the ketimine (o-HOC6H4)C(Me)=NCH2Ph catalyzed by the [Rh(COD)(PPh3)(2)]PF6 precursor in MeOH at ambient conditions, we have isolated [Rh{eta(4)-(C6H4O)C(-)(Me)=N(+)(H)CHPh}(PPh3)(2)]PF6 (3), an unusual zwitterionic Rh complex in which the imine is coordinated via the C-4 part of the o-hydroxy-arene moiety in a quinoid form; this tautomer is generated via proton transfer from the O-atom to the N-atom within the molecular, benzenoid form. Precipitation of 3 from the MeOH solution, even under H-2, causes sequestration of the Rh and complete suppression of the catalytic activity. (In a previously studied system with the corresponding, non-hydroxy-substituted ketimine, PhC(Me) = NCH2Ph, the Rh was sequestered as an inactive o-metalated species). The solid state structure of 3 is retained in CH2Cl2 solution, but in MeOH and Me2CO reversible loss of the ketimine generates the cis-[Rh(PPh3)(2)(solvent)(2)]PF6 species. (c) 2006 Elsevier B.V.

Activation of other terminal alkynes by ([NPN]Ta)(2)(mu-H)(4) accesses ([NPN]Ta)(2)(mu-RCCH)(mu-H)(2) (R = n-Pr, t-Bu).

Storage of solutions of ([NPN]Ta)(2)(mu-PhCCH)(mu-H)(2) under vacuum promotes the loss of H-2 and cleavage of the C-C bond to give a bis(mu-alkylidyne) complex, ([NPN]Ta)(2)(mu-CPh)(mu-CH).

Vibrational characterization of the Ta-2(mu-N-2)(mu-H)(2) core is based on resonance Raman and infrared spectroscopies evaluated with a novel quantum chemistry-based normal coordinate analysis (QCB-NCA). The N-N stretching frequency is found at 1165 cm(-1) exhibiting a N-15(2) isotope shift of -37 cm(-1). Four other modes of the Ta2N2H2 core are observed between 430 and 660 cm(-1). Two vibrations of the bridging hydrido ligands are also identified in the spectra. On the basis of experimental frequencies and the QCB-NCA procedure, the N-N force constant is determined to be 2.430 mdyn -Angstrom(-1). The Ta-N force constants are calculated to be 2.517 mdyn Angstrom(-1) for the Ta-eta(1)-N-2 bond and 1.291 and 0.917 mdyn Angstrom(-1) for the Ta-eta(2)-N-2 bonds, respectively. DFT calculations on 1 suggest that the bridging dinitrogen ligand carries a charge of -1.1, which is equally distributed over the two nitrogen atoms. However, orbital analysis reveals that the terminal nitrogen makes lower contributions to the pi orbitals and much higher contributions to the pi* orbitals of the N-2 ligand than the bridging nitrogen. This suggests that reactions of the dinitrogen ligand with electrophiles should preferentially occur at the terminal N atom, in agreement with experimental results.},

	abstract = {Electronically and coordinatively unsaturated [Cp*W(NO)(L)] complexes have been postulated as intermediates in several related systems. Model [CpW(NO)(L)] compounds (L= PH3, CO, CH2, H2CCH2, HCCH) have been investigated theoretically by means of density functional theory computational techniques. The structural parameters calculated for saturated [CpW(NO)(PH,)(L)] complexes are in good agreement with the solid-state molecular structures determined crystallographically for the corresponding [Cp*W(NO)(PMe3)(L)] compounds. The 16-electron, singlet [CpW(NO)(L)] species have geometries comparable to those of the same fragment in the phosphine adducts and include a highly pyramidal conformation at W. The energy of the triplet spin state is calculated to be close to or even lower than that of the singlet state for these unsaturated compounds, and depends largely on the pi-bonding capabilities of L (Delta Es-t=Delta E-t-Delta E-s = - 3.3 kcalmol(-1) (PH3), + 2.8 (CO), + 2.4 (CH2), +6.3 (H2CCH2), -2.3 (HCCH)). The optimization of partially constrained structures in both spin states allows for a conformational analysis of the [CpW(NO)(L)] species. The inversion of the conformation of the pyramidal singlet [CpW(NO)(L)] complexes via the planar-at-W triplet species (two-state pathway) is calculated to be competitive with the equivalent process solely along the singlet spin hypersurface. Rotation of the W-CH, bond in the singlet carbene species is also found to proceed more readily via a two-state pathway. The preferred alkyne conformation, the unusually stable triplet states, and the strong W-to-L sc-donation observed in these systems may all be rationalized by the relatively high energies of the occupied orbitals of the formally WO compounds.},

	abstract = {Thermal activation of Cp*W(NO)(eta(2)-CPhCH2)(CH2SiMe3) (1) in neat hydrocarbon solutions transiently generates Cp*W(NO)(eta(2)-PhC=CH) (A), which subsequently activates solvent C-H bonds. For example, the thermolysis of 1 in benzene solution generates quantitatively Cp*W(NO)(eta(2)-CPhCH2)(Ph) (2) The thermolysis of 1 in solutions of methyl-substituted arenes such as toluene or p-, m-, or o-xylene provides mixtures of aryl and benzyl vinyl complexes of the general formulas Cp*W(NO)(eta(2)-CPhCH2)(aryl), Cp*W(NO)(eta(2)-CPhCH2)(eta(1)-benzyl), or Cp*W(NO)(eta(2)-benzyl)(eta(1)-CPh=CH2). Similarly, the thermolysis of 1 in (Me3Si)(2)O affords Cp*W(NO)(eta(2)-CPhCH2)(CH2SiMe2OSiMe3) (10). Mechanistic and kinetic studies support the proposal that the formation of A from 1 by elimination of silane is the rate-controlling process in these reactions. Intra- and intermolecular selectivity studies reveal that the strongest C-H bond (yielding the stronger M-C bond) is the preferred site of reactivity, as expected. Dual C-H bond activation of aliphatic hydrocarbons occurs during the thermal activation ;of I in solutions of these substrates. Consequently, metallacycles of the form Cp*W(NO)(eta(2)-CH(eta(2)-Ph)CH2CH(R)CH2) [(11)R = Pr-n; (12)R = Bu-n; (13)R = Bu-t; and (14)R = OEt] result from the dehydrogenation of n-pentane, n-hexane, 2,2-dimethylbutane, and diethyl ether, respectively. This dual C-H activation process displays a selectivity for substrates that contain an ethyl substituent. Dual C-H bond activation of 2,3-dimethyl-2-butene in the presence of 1 under thermolysis conditions regioselectively affords Cp*W(NO)(eta(3)-endo-CH2C(Me)C(Me)CH2(eta(1)-CPhMe)) (15), Attempts to trap acetylene complex A with PNMe3 result in the formation of the metallacyclopropane complex Cp*W(NO)(CH2SiMe3)(eta(2)-CH2CPh(PMe3)) (16). All new complexes have been characterized by conventional spectroscopic methods, and the solid-state molecular structures of compounds 11, 15, and 16 have been established by X-ray diffraction methods.},

For this purpose, a tripodal dodecadentate Ligand incorporating three salicylamide (OO) and three bipyridine (NN) binding sites was synthesized as well as iron complexes thereof. It was shown that a ferric ion coordinates selectively to the hard salicylamides and a ferrous ion binds to the softer bipyridines. Upon reduction or oxidation, the iron translocates reversibly and intramolecularly from one site to the other, thus displaying switchlike properties. Both states were characterized by cyclic voltammetry and visible and Mossbauer spectroscopy. The Mossbauer spectrum for the ferric complex is fully consistent with that obtained by Pecoraro et al. upon lowering the pH of [Fe-III(enterobactin)](3-) solutions (Pecoraro, V. L., et al. J. Am. Chern. Sec. 1983, 105, 4617), thus supporting the alternative iron release mechanism from enterobactin via the salicylate binding mode.},

Thermolysis of this mixture yields the alkylidene complex [P2Cp]Zr=CHPh(Cl) (5) in 85\% overall yield. Kinetic studies reveal a composite mechanism that incorporates the above preequilibrium, followed by an intramolecular alpha-abstraction reaction of dibenzyl 3 which follows a first-order rate, with the rate parameters Delta H double dagger = 19(1) kcal mol(-1) and Delta S double dagger = -22(5) cal(-1) mol K-1. A kinetic isotope effect of 3.0(5) was measured at 70 degrees C for the perdeuterated analogue [P2Cp]ZrCl(CD2C6D5)2. The reaction of 1 with 2 equiv of LiCH2-EMe3 (E = C, Si) produces a similar equilibrium mixture as observed for the benzyl analogues, consisting of [P2Cp]ZrCl2(CH2EMe3) (7), [P2Cp]Zr(CH2EMe3)(3) (8), and [P2Cp]ZrCl(CH2EMe3)(2) (9). Thermolysis of this mixture yields [P2Cp]Zr=CHEMe3(Cl) (6). A kinetic analysis conducted on 9 (E = Si) indicated a first-order reaction from which the activation parameters Delta H double dagger = 6(1) kcal mol(-1) and Delta S double dagger = -62(5) cal mol(-1) K-1 were obtained. The results indicate that reaction rates follow the order CH2Ph > CH2SiMe3 > CH2CMe3, an exact reversal of the trend for the homoleptic Ta systems Ta(CH2R)(5). The role of phosphine coordination is discussed to account for this trend. A crystal structure determination obtained for 6b reveals an alpha-agnostic interaction and a structure analogous to that of 5.},

Reaction of these halide complexes with organolithium, sodium, or potassium reagents generates square-planar, low-spin hydrocarbyl complexes of the formula CoR[N(SiMe2CH2PPh2)(2)] (R = Me, CH2Ph, CH2SiMe3, C5H5). One-electron oxidations have been carried out; only the product of halide abstraction is observed. For example, addition of PhCH2X to the halide derivatives CoX[N(SiMe2CH2PPh2)(2)] generates trivalent, paramagnetic complexes, CoX2[N(SiMe2CH2PPh2)(2)]; these derivatives show variable-temperature magnetic susceptibility data that are consistent with zero-field splitting of the S = 1 state. Addition of methyl bromide or methyl iodide to low-spin CoMe[N(SiMe2CH2PPh2)(2)] results in the formation of the Co(II) halide derivatives CoX[N(SiMe2CH2PPh2)(2)] along with methane and bibenzyl. It is proposed that the Co(III) methyl halide complex CoMe(X) [N(SiMe2CH2PPh2)(2)] is unstable and loses methyl radical homolytically to generate the Co(II) halide derivative; the methyl subsequently reacts with the toluene solvent to produce methane and bibenzyl. Addition of excess benzyl halides has also been found to generate the Co(II) halide complexes initially, followed by a one-electron oxidation to the Co(II) dihalide derivatives. In much of the one-electron chemistry of the Co(II) derivatives incorporating the amidodiphosphine ligand, the decomposition of the putative but unstable Cs(III) alkyl halide derivative CoRX[N(SiMe2CH2PPh2)(2)] is proposed as a recurring event.},

	abstract = {[Cp*Mo(NO)(CH2SiMe3)(2)] exhibits three principal types of reaction with the various lithium reagents investigated during this study, namely: regioselective deprotonation, reduction, and addition. Deprotonation of the reactant, achieved by treatment with lithium amide reagents, leads ultimately to the formation of the alkylidene {\textquoteright}{\textquoteright}ate{\textquoteright}{\textquoteright} complex [Cp*Mo(NO)(CH2SiMe3)(=CHSiMe3)](2)[Li-2(thf)(3)] (1). While LiN(SiMe3)(2) effects this conversion directly with no detectable intermediates, reaction with 1 equiv of LDA in THF for 15 min deprotonates the Cp* ligand to form the lithium salt of the {\textquoteright}{\textquoteright}tucked-in{\textquoteright}{\textquoteright} ate complex [(eta(5),eta(1)C(5)Me(4)CH(2))Mo(NO)(CH2SiMe3)(2)][Li(thf)(3)] (2) in 40\% isolated yield, Complex 2 slowly converts to the thermodynamically more stable 1 when left as a THF or C6D6 solution at ambient temperature fbr 48 h. Reaction of the dialkyl starting material with either tBuLi or PhLi leads to the production of the alkylidene complex 1 in irreproducible yields (10-50\% NMR; not isolable). A kinetic analysis of the reaction of [Cp*Mo(NO)(CH2SiMe3)(2)] with LiN(SiMe3)(2) indicated that the reaction was first-order in both the lithium and molybdenum reagents, and the activation parameters of Delta H-double dagger = 7,3 +/- 1.0 kcal mol(-1) and Delta S (double dagger) = -34 +/- 3 e.u. suggest an associative process. Treatment of the neutral dialkyl with 1 equiv of LiPPh2, in THF results in a one-electron reduction and production of {[Cp*Mo(NO)(CH2SiMe3)(2)][Li(thf)]}(2) (3). If left in solution, the 17e(-) dialkyl anion 3 is converted to the 18e(-) alkylidene anion 1 by the Ph2P-PPh2 coproduct, which effects the requisite hydrogen-atom abstraction. Finally, addition of a sterically undemanding alkyllithium reagent such as MeLi to the 16e(-) dialkyl reactant leads to the formation of the 18e(-) trialkyl anionic complex [Cp*Mo(NO)(CH2SiMe3)(2)(Me)][Li(thf)(3)] (4). Warming of 4 in a C6D6 solution results in loss of methane and production of 1. In most cases, the chemistry exhibited by the Mo system is duplicated by the analogous W congener, [Cp*W(NO)(CH2SiMe3)(2)]. The solid-state molecular structures of complexes 1 and 4 have been established by single-crystal X-ray crystallographic analyses.},

C-13 NMR spectroscopy also establishes that the low-temperature limiting structures of the complexes in solution are identical with their solid-state molecular structures. Interestingly, the tungsten bis(benzyl) complexes exhibit the more facile fluxional processes in solution, this increased nonrigidity apparently rendering the tungsten complexes more reactive to Lewis bases.

The analogous lanthanum derivative requires the use of the corresponding potassium salt KN(SiMe2CH2PR2)2 (R = Me, Ph) with anhydrous LaCl3 to generate good yields of LaCl(N(SiMe2CH2PR2)2]2.

The reactions of 1 and 2 with olefins (ethylene, maleic anhydride, diethyl maleate, and olefinic nitriles) are studied and some square-planar Pt(PR3)2(eta-2-olefin) species isolated (PR3 = the pyridylphosphine). No olefin hydration products are observed on heating the olefin complexes in aqueous solution. Oxidative addition of MeI to 1 and to 2 gives the trans-PtI(Me)(PR3)2 species. However, the trans-Pt(H)Cl(PR3)2 species is isolated only from reaction of 2 with gaseous HCl; the hydride reacts with acrylonitrile to form cis-PtCl(CH2CH2CN)(PR3)2.},
