Cleavage of metal-carbon bonds in hydride-bridged platinum and palladium A-frame complexes

Journal Article Xu, C ; Anderson, G K - Organometallics

The hydride-bridged A-frame complexes [RPt({mu}-H)({mu} -dppm){sub 2}PtR`]PF{sub 6} and [RPt({mu}-H)({mu}-dppm){sub 2} PdR`]PF{sub 6} react with HCL (generated by reaction of acetyl chloride with water) in acetone-d{sub 6} solution by cleavage of one of the metal-carbon bonds. In the diplatinum systems the relative rates of Pt-C bond cleavage decrease in the order Me > Et > Ph, resulting in a single product in each case. For the heterometallic complexes reaction is faster at palladium, but mixtures of [RPt({mu}-H)({mu}-dppm){sub 2}PdCl]PF{sub 6} and [ClPt({mu}-H)({mu}-dppm){sub 2}PdR`]PF{sub 6} result in several instances. Further reaction of these with HCl and/or CCl{sub 4} generates the chloride-bridged speciesmore »« less

Palladium bis-pincer complexes with controlled rigidity and inter-metal distance

Journal Article Yu, Cheng-Han ; Zhu, Congzhi ; Ji, Xiaozhou ; ... - Inorganic Chemistry Frontiers (Online)

We report a series of redox-active bis(pincer) Pd( ii ) complexes in which the redox active units are based on either a diarylamido or a carbazolide framework.

Metal-to-metal silyl migration and silicon-carbon bond cleavage/re-formation processes in the methylene/silyl complexes Cp{sup *}{sub 2}Ru{sub 2}({mu}-CH{sub 2})(SiR{sub 3})({mu}-Cl)

Journal Article Shelby, Q D ; Lin, W ; Girolami, G S - Organometallics

Ruthenium methylene/silyl complexes of stoichiometry Cp{sup *}{sub 2}Ru{sub 2}({mu}-CH{sub 2})(SiR{sub 3})({mu}-Cl), where SiR{sub 3} = SiMe{sub 3} (1), SiEt{sub 3} (2), SiMe{sub 2}Et (3), and SiMe{sub 2}Ph (4), are produced when [Cp{sup *}RuCl]{sub 4} is treated with the appropriate dialkylmagnesium reagent, Mg(CH{sub 2}SiR{sub 3}){sub 2}. Each complex undergoes two fluxional processes as observed by variable-temperature {sup 1}H NMR spectroscopy. The low-temperature exchange process is migration of the SiR{sub 3} unit from one Ru center to the other, whereas the high-temperature process is the reversible re-formation of the C-Si bond between the silyl group and the bridging methylene unit.

Carbon-nitrogen bond cleavage in an {eta}{sup 2}(N,C)-pyridine complex induced by intramolecular metal-to-ligand alkyl migration: Models for hydrodenitrogenation catalysis

Journal Article Gray, S D ; Weller, K J ; Bruck, M A ; ... - Journal of the American Chemical Society

The reaction of the {eta}{sup 2}(N,C)-pyridine complex with LiBEt{sub 3}H affords the C-N bond scission product (2). The reactions of (1) with carbon nucleophiles RLi or RMgX provide the alkyl derivatives [R = Me (3), Et (4), {sup n}Pr (5), {sup n}Bu (6), and CH{sub 2}SiMe{sub 3} (7)]. Kinetic and mechanistic studies of the 3 {yields} 8 rearrangement reveal that methyl migration is strictly intramolecular. The reactions of this model system delineate one process by which heterocyclic C-N bonds are cleaved and offer new insight as to how nitrogen heterocycles may be further degraded after C-N bond cleavage in hydrodenitrogenationmore » catalysis. 74 refs., 7 figs., 5 tabs.« less

Carbon-fluorine bond cleavage by zirconium metal hydride complexes

Journal Article Edelbach, B L ; Rahman, A K.F. ; Lachicotte, R J ; ... - Organometallics

The use of transition metal complexes to cleave strong carbon-fluorine bonds has blossomed in the past several years. Many late transition metal complexes with electron-donating ligands are believed to undergo oxidative addition to the C-F bond of a fluorinated aromatic group. The zirconium hydride dimer [Cp{sub 2}ZrH{sub 2}]{sub 2} reacts with C{sub 6}F{sub 6} at ambient temperature to give Cp{sub 2}Zr(C{sub 6}F{sub 5})F as the major product along with Cp{sub 2}ZrF{sub 2}, C{sub 6}F{sub 5}H and H{sub 2}. Neither the reaction rate nor the product ratio is affected by changes in H{sub 2} pressure or the concentration of C{sub 6}F{submore »« less
