Abstrakt: [RuClH(CO)(PPh3)3] (1) reacted with alkyl allyl sulfides at 10–25 °C to give insertion products, [Ru(CH2CH2CH2SR)Cl(CO)(PPh3)2] (R = CH3, 2; R = CH2C6H5, 3; and R = CH2CH=CH2, 4). Complexes 2–4exhibited temperature-dependent NMR spectra above −40 °C, indicating that rapid exchange occurred between two structural isomers owing to inversion of the alkyl group upon the coordinated sulfur stom. Upon heating at 67 °C, 2was converted into a binuclear complex, [Ru2(μ-Cl)Cl(μ-H)(μ-SCH3)(CO)2(PPh3)3], evolving propylene. Complex [RuClH(CO)(dppe)(PPh3)] (7) [dppe = 1,2-bis(diphenylphosphino)ethane] reacted with allyl methyl sulfide at 110 °C to afford [Ru2Cl2(μ-SMe)2(CO)2(dppe)2] (8), evolving propylene.
