	abstract = {A theory based on dynamic complexation is used to describe analyte migration behavior in capillary electrophoresis (CE). This theory is based on a one-phase system, instead of the commonly accepted two-phase system. The migration behavior of an analyte is described by three parameters (the electrophoretic mobility of the free analyte, the electrophoretic mobility of the analyte-additive complex, and the equilibrium constant (formation constant) that determines the fractions of the free analyte and the complex at a certain additive concentration). Varying the additive concentration shifts the equilibrium and changes the viscosity of the background electrolyte. Viscosity correction is crucial in interpreting the observed migration behavior of analytes. While electroosmotic flow in a capillary often varies from one capillary to another, the viscosity of a buffer is characteristic of the buffer composition and is constant for each buffer. The electrophoretic mobility of a certain species and the equilibrium constant are intrinsic properties and are less sensitive to changes in the environment. Understanding these relationships is indispensable in CE method development and method validation. A universal resolution equation is proposed, with a separation factor that has taken both the electrophoretic mobilities and equilibria into consideration. This resolution equation gives clear guidance for the optimization of CE separations. A group of nucleosides and their phosphates are used as analytes, and P-cyclodextrin is used as the additive in the model system studied in this paper. Both the observed analyte migration behavior and the resolution of analytes agree well with this theory.},

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.

	abstract = {Treatment of solutions of Cp*W(NO)(CH(2)SiMe(3))(2) with H-2 generates in situ the reactive 16-valence-electron alkyl hydride Cp*W(NO)(CH(2)SiMe(3))H, formed by hydrogenolysis of one of the W-C sigma-bonds of the dialkyl reactant. The Lewis-acidic hydride complex has not yet been isolated, but its existence has been inferred on the basis of the varied chemical reactions that it undergoes when generated in the presence of reactive substrates. PPh(3) affords the orthometalated complex Cp*W(NO)(H)(PPh(2)C(6)H(4)) as a yellow crystalline solid probably via the 18-electron adduct Cp*W(NO)(CH(2)SiMe(3))(PPh(3))H. Consistently, the same reaction effected with PPh(3)-d(15) results in complete deuteration of the hydride position in the product. Acyclic, conjugated dienes such as butadiene or 2,3-dimethyl-1,3-butadiene afford Cp*W(NO)(eta(4)-trans-diene) complexes. The characteristic chemistry of Cp*W(NO)(CH(2)SiMe(3))H is, however, dominated by the ability of its W-H link to insert unsaturated linkages, the regioselectivity of the insertions indicating that the hydride Ligand is hydridic in nature. For instance, insertion of acetonitrile affords the ethylideneamido complex Cp(*)W(NO)(CH(2)SiMe(3))(N=CHMe), which is isolable as a diastereomeric pair. Similarly, insertions of organic reagents containing carbonyl (O=C) or imine (HN=C) functional groups produce the corresponding alkyl alkoxide or alkyl amide products, respectively, in virtually quantitative yields. Phenylacetylene affords the novel alkyl alkenyl compound Cp*W(NO)(CH(2)SiMe(3))(CPh=CH2), which is thermally unstable and isolable in only low yields. Insertions into the W-H bond by other olefinic substrates are successful only if the unsaturated hydrocarbon also contains a Lewis-base functional group. Thus, propargylamine and allylamine produce the related metallacyclic complexes Cp*W(NO)(CH(2)SiMe(3))(NH2CH2CHCH) and Cp*W(NO)(CH(2)SiMe(3))(NH2CH2CH2CH2), respectively. Treatment of Cp*W(NO)(CH(2)SiMe(3))(2) with H-2 in the presence of allyl alcohol does not produce an oxometallacycle, but rather affords the allylalkoxo complex resulting from the alcohol simply functioning as a protonic acid toward the dialkyl reactant. The solid-state molecular structures of Cp*W(NO)(CH(2)SiMe(3))(N=CHMe) and Cp*W(NO)(CH(2)SiMe(3))(NH2CH2CH2CH2) have been established by single-crystal X-ray crystallographic analyses. Crystals of Cp*W(NO)(CH(2)SiMe(3))(N=CHMe) are monoclinic of space group P2(1)/n: a = 9.515(2) Angstrom; b = 21.946(3) Angstrom; c = 9.552(2) Angstrom; Z = 4; V = 1946.8 Angstrom(3); T = 200 K; R(f) = 0.029 for 2035 data (I-0 greater than or equal to 2.5 sigma(I-0)) and 106 variables.

The diphosphines (PP) used include chiral (chiraphos, diop, binap) and achiral (dppe, dppb) systems (chiraphos = Ph2PCH(Me)CH(Me)PPh2; diop = Ph2PCH2CHOCMe2OCHCH2PPh2; binap = 2,2{\textquoteright}-bis(diphenylphosphino)-1,1{\textquoteright}-binaphthyl; Ph2P(CH2)(n)PPh2 (n = 2, dppe; n = 4, dppb)). Activity was observed in MeOH at low catalyst concentrations (0.77 mM Ru), under moderate conditions (room temperature (r.t.), 1000 psi H2). The air-stable Ru2Cl5(PP)2 complexes were more active than the commonly used dimeric Ru2(II,II) systems to which they give rise in situ. Asymmetric induction in the prochiral ketimine PhCH2N = C(Me)Ph was consistent, though modest, within the diop and binap series of neutral complexes, implying a common catalytic intermediate within each series. A maximum e.e. of 27\% was found using Ru2Cl5(chiraphos)2 as catalyst; this represents a non-optimized figure for asymmetric induction, as no other prochiral ketimines were screened.},

	abstract = {The syntheses of the binary fluorosulfates, Zr(SO3F), and Hf(SO3F)4, by oxidation of the corresponding metal powders with bis(fluorosulfuryl) peroxide, S2O6F2, in fluorosulfuric acid, HSO3F, are described. The resulting products are white hygroscopic solids which are not sufficiently soluble in HSO3F to allow electrical conductivity and NMR studies or Hammett acidity function (H-0) determinations in order to evaluate their use as Lewis acids in conjugate superacid systems. Oxidation of titanium under similar conditions resulted in the formation of a greenish-yellow resin-like material of limited thermal stability with the approximate composition Ti(SO3F)4. However, infrared spectra indicated the presence of small amounts of HSO3F. In addition, the solvolysis of ZrCl4 in an excess of HSO3F at 25-degrees-C has been investigated as a potential route to Zr(SO3F)4. The results indicate that short reaction times of 1-2 d yielded incompletely substituted products of the approximate composition ZrClx(SO3F)4-x (x = 0.22), while prolonged reaction times of 3-4 weeks gave rise to partially decomposed materials of approximate composition ZrO0.5F1.5(SO3F)1.5. The ability of all three tetrakis(fluorosulfato) metallates to act as SO3F- ion acceptors is evident from the isolation of thermally stable salts of the composition Cs2[M(SO3F)6] (M = Ti, Zr or Hf) when the metal oxidation was carried out in the presence of 2 mol equiv. of CsSO3F. All the materials were characterized by their vibrational spectra, which are extremely similar and closely resemble those of previously reported cesium hexakis(fluorosulfato) metallates.},
