	abstract = {Reactions of a variety of cyclic and acyclic olefins with the title alkylidene complex (formed spontaneously by loss of neopentane from Cp*Mo(NO)(CH2CMe3)(2) under ambient conditions) result in the initial formation of molybdenacyclobutane complexes (Cp* = C5Me5). These molybdenacyclobutane complexes do not react via olefin metathesis or cyclopropanation pathways, but instead via C-H activation. Thus, when cyclopentene is the olefinic substrate, the direct result of C-H activation at the beta-position of the metallacyclobutane affords a thermally stable allyl hydrido complex that can be isolated. Such an allyl hydride intermediate is not isolable for larger cyclic olefins (cyclohexene, cycloheptene, and cyclooctene) or acyclic olefins (allylbenzene and 1-hexene). Instead, those complexes react further, undergoing a second C-H activation at the allylic position to produce eta(4)-trans-diene complexes concomitant with the loss of dihydrogen. Upon heating, these eta(4)-trans-diene complexes liberate diene, thereby enabling the 14e Cp*Mo(NO) metal fragment to catalyze the oligomerization of cyclic olefins and dienes including cyclohexene and 1,4-cyclohexadiene. In the case of the acyclic olefin allylbenzene, the metal fragment catalyzes a dimerization to (E)-(4-methylpent-1-ene-1,5-diyl)dibenzene under ambient conditions.},

	abstract = {This report describes investigations that have elucidated the nature, extent, and mechanism of the cyclic-olefin oligomerization effected by a series of tungsten precatalysts, with particular focus on Cp*W(NO)(CH2CMe3)(2) (1) and Cp*W(NO)(CH2SiMe3)(eta(2)-CPhCH2) (2). Upon thermolysis, these precatalysts oligomerize simple cyclic olefins, from cyclopentene to cyclooctene, into ring-retaining oligomers as high as dodecamers (depending on the substrate) with remaining sites of unsaturation. Precatalyst initiation involves the coupling of one equivalent of the substrate with the reactive 16e intermediate thermally generated by the precatalyst (i.e., an alkylidene by 1 or an eta(2)-alkyne complex by 2), followed by rearrangement of the coupled ligand in the metal{\textquoteright}s coordination sphere either to an olefin or to a diene (with concomitant loss of two hydrogen atoms). The rearranged ligand is displaced from the metal center as two equivalents of substrate coordinate to form a putative bis-olefin complex, Cp*W(NO)(cyclic olefin)2, that represents the convergent entry point to the catalytic cycle for the precatalysts. The coordinated olefins undergo metal-mediated coupling to form a metallacyclopentane complex. The metallacycle then undergoes beta-hydrogen activation and reductive elimination to generate an eta(2)-cyclic-olefin dimer. Further incorporation of substrate leads to formation of trimers and higher oligomers. Alternatively, expulsion of any coordinated oligomer from the tungsten center regenerates the reactive bis-olefin complex. Finally, decomposition of the tungsten catalyst species is consistent with a bimetallic pathway. All new organometallic complexes have been characterized by conventional spectroscopic and analytical methods, and the solid-state molecular structures of several compounds have been established by X-ray crystallographic analyses.},

	abstract = {RS1, also known as retinoschisin, is an extracellular protein that plays a crucial role in the cellular organization of the retina. Mutations in RS1 are responsible for X-linked retinoschisis, a common, early-onset macular degeneration in males that results in a splitting of the inner layers of the retina and severe loss in vision. RS1 is assembled and secreted from photoreceptors and bipolar cells as a homo-oligomeric protein complex. Each subunit consists of a 157-amino acid discoidin domain flanked by two small segments of 39 and 5 amino acids. To begin to understand how the structure of RS1 relates to its role in retinal cell adhesion and X-linked retinoschisis, we have determined the subunit organization and disulfide bonding pattern of RS1 by SDS gel electrophoresis, velocity sedimentation, and mass spectrometry. Our results indicate that RS1 exists as a novel octamer in which the eight subunits are joined together by Cys(59)-Cys(223) intermolecular disulfide bonds. Subunits within the octamer are further organized into dimers mediated by Cys(40)-Cys(40) bonds. These cysteines lie just outside the discoidin domain indicating that these flanking segments primarily function in the octamerization of RS1. Within the discoidin domain, two cysteine pairs (Cys(63)-Cys(219) and Cys(110)-Cys(142)) form intramolecular disulfide bonds that are important in protein folding, and one cysteine (Cys(83)) exists in its reduced state. Because mutations that disrupt subunit assembly cause X-linked retinoschisis, the assembly of RS1 into a disulfide-linked homo-octamer appears to be critical for its function as a retinal cell adhesion protein.},

Reduction of 2, 3 or 4 using C8K or activated magnesium decomposed the complexes in such a manner that the ligand was separated from the metal centre.

This latter domain adopts a beta-trefoil structure with three potential binding sites (alpha, beta, and gamma) for a variety of small sugars, xylooligosaccharides, and xylan polymers. To investigate the role of this multivalency in carbohydrate binding, we have used NMR spectroscopy to characterize the interaction of isolated CBM13 with a series of sugars. We have assigned resonances from the main chain nuclei of CBM13 using heteronuclear NMR experiments. Analysis of N-15 NMR relaxation data using the extended model free formalism reveals that CBM13 tumbles as an oblate ellipsoid (D-\/D-perpendicular to = 0.80+/-0.02) and that its backbone is relatively rigid on the sub-nanosecond time scale. In particular, the three binding sites show no distinct patterns of increased internal mobility. Ligand-induced chemical shift changes in the H-1-N-15 HSQC spectra of CBM13 were monitored as a function of increasing concentrations Of L-arabinose, lactose, D-xylose, xylobiose, xylotetraose, and xylohexaose. Patterns of shift perturbations for well-resolved resonances demonstrate that all of these sugars associate independently with the three binding sites of CBM13. On the basis of the site-specific association constants derived from a quantitative analysis of these titration data, we show that L-arabinose, lactose, and D-xylose preferentially bind to the alpha site of CBM13, xylobiose binds equally well to all three sites, and xylotetraose and xylohexaose prefer binding to the beta site.

Unlike related 16-electron CpMo(NO)R-2 complexes, these 18-electron species exhibit good thermal stability due to their eta (2)-benzyl-Mo interactions. Treatment of CpMo(NO)(CH2Ph)Cl with Na(DME)Cp provides dark green Cp2Mo(NO)(CH2Ph), whose solid-state molecular structure has been established by a single-crystal X-ray crystallographic analysis. The two Cp rings display different binding modes to the Mo atom, while the benzyl ligand is coordinated to the metal centre in an eta (1) fashion. The triflate complex, CpMo(NO)(CH2Ph)(OTf), is obtained by addition of AgOTf to the benzyl chloride precursor. The covalent Mo-OTf bond in this compound can be disrupted by the addition of Lewis bases (L) such as PPh3 or pyridine, leading to the corresponding [CpMo(NO)(CH2Ph)(L)][OTf] salts. Attempts to generate neutral benzylidene complexes by deprotonation of [CpMo(NO)(CH2Ph)(PPh3)][OTf] have not yet been successful.},

The methylidene precursor [P2N2]TaMe3 is generated by the reaction of [P2N2]Li-2. C4H8O2 (C4H8O2 = 1,4-dioxane) with TaMe3Cl2. The solid-state X-ray molecular structure demonstrates that the geometry of [P2N2]TaMe3 is a seven-coordinate capped trigonal prism, and NMR studies confirm this is also true in solution at low temperature. Photolysis with a UV source generates [P2N2]Ta=CH2(Me), with the elimination of methane. The X-ray solid-state molecular structure of [P2N2]Ta=CH2(Me) is intermediate between octahedral and trigonal-prismatic geometry. Variable-temperature NMR studies demonstrate that the double-bonded methylidene moiety rotates with a barrier of 33.5 +/- 0.6 kJ/mol, in contrast to the larger barrier estimated for the previously characterized 18-electron complex (eta(5)-C5H5)(2)Ta=CH2(Me).

The crystal structure of 5, previously determined, shows the phenyl groups are trans to the Ru-3-triangle; in 6 they are probably cis and on the same side of the Ru-3-triangle as the benzyne moiety.

The resulting white solids are the first examples of metal carbonyl derivatives formed by a post-transition element. Both salts are characterized by FT-IR, FT-Raman, and C-13-MAS-NMR spectroscopy. For [Hg(CO)(2)][Sb2F11], unprecedentedly high CO stretching frequencies (<(nu)over bar>(av) = 2279.5 cm(-1)) and stretching force constant (f(r) = 21.0 +/- 0.1) x 10(2) Nm(-1)) are obtained. Equally unprecedented is the (1)J(C-13-Hg-199) value of 5219 +/- 5 Hz observed in the C-13 MAS-NMR spectrum of the C-13 labeled isotopomers at delta = 168.8 +/- 0.1 ppm. The corresponding values (<(nu)over bar>(av) = 2247 cm(-1), f(r) = (20.4 +/- 0.1) x 10(2) Nm(-1), (1)J(C-13-Hg-199) = 3350 +/- 50 Hz and (2)J(C-13-Hg-199) 850 +/- 50 Hz) are found for [Hg-2(CO)(2)][Sb2F11](2), which has lower thermal stability (decomposition point in a sealed tube is 140 degrees C vs 160 degrees C for the Hg(II) compound) and a decomposition pressure of 8 Torr at 20 degrees C. The mercury(I) salt is sensitive toward oxidation to [Hg(CO)(2)][Sb2F11](2) during synthesis. Both linear cations (point group D infinity h) are excellent examples of nonclassical (sigma-only) metal-CO bonding.

The Hg atom lies on a crystallographic inversion center. The Hg-C-O angle is 177.7(7)degrees. The length of the mercury-carbon bond is 2.083(10) Angstrom and of the C-O bond 1.104(12) Angstrom respectively. The structure is stabilized in the solid state by a number of significant secondary interionic Hg{\textendash}-F and C{\textendash}-F contacts.},

	abstract = {{The preparation, solid-state structures, and magnetic properties of two new Cr(II) amido diphosphine complexes are described. Reaction of the lithium salt LiN(SiMe(2)CH(2)PPh(2))(2) with CrCl2.THF results in the formation of the dinuclear chloride-bridged species {[(Ph(2)PCH(2)SiMe(2))(2)N]Cr}(2)(mu-Cl)(2), 1. This complex is paramagnetic at room temperature with a magnetic moment corresponding to four unpaired electrons per chromium; however, as the temperature is lowered, magnetic susceptibility measurements show that 1 exhibits antiferromagnetic behavior with J = -12.4 cm(-1) and g = 1.99. Chloride 1 can be converted to the mononuclear methyl complex CrMe[N(SiMe(2)CH(2)PPh(2))(2)] by reaction with MeLi. Under a hydrogen atmosphere, the methyl complex is converted to the dinuclear hydride derivative {[(Ph(2)PCH(2)SiMe(2))(2)N]Cr}(2)(mu-H)(2), 3. A variable temperature magnetic susceptibility study shows that this species is very strongly antiferromagnetically coupled with J = -139 cm(-1) and g = 1.98. The magnetic coupling correlates with the Cr-Cr distances observed in the solid state for these complexes: for 1, the Cr-Cr distance is 3.64 while for the hydride 3 a much shorter distance of 2.641 Angstrom is found. Crystals of {[(Ph(2)PCH(2)SiMe(2))(2)N]Cr}(2)(mu-Cl)(2), 1, are triclinic},

	abstract = {The rotational spectrum of the most abundant isotopomer of thionyl chloride, S-32 O-16 Cl-35(2), has been recorded in the frequency range 7.8-24.7 GHz using a pulsed molecular-beam microwave spectrometer. 262 lines of 27 rotational transitions (b- and c-type) have been used to determine rotational and quartic centrifugal distortion constants and the complete Cl-35 nuclear quadrupole coupling tenser, as well as spin-rotation coupling constants. Whereas the diagonal quadrupole coupling constants in the inertial axis system agree with those from previous microwave studies, disagreement is observed for the principal values chi(zz) (-63.8 MHz) and eta (-0.0143). However, the value of chi(zz) is in good agreement with those derived from solid-state NQR measurements. The centrifugal distortion constants together with vibrational wavenumbers and amplitudes have been used to refine the harmonic force field. The principal quadrupole coupling constants and the force constants are compared with those of related molecules, and the latter have been used to propose a reassignment of two vibrational bands of the related molecule, SO2Cl2.},
