Abstract: A series of novel monothiolate-bridged dirhodium complexes, [Cp*Rh(mu-SR)(mu-Cl)(2)RhCp*][BF4] {Cp* = eta(5)-C5Me5, R = tertiary butyl (Bu-t), 1a; R = ferrocenyl (Fc), 1b; R = adamantyl (Ad), 1c} were designed and successfully synthesized, which can smoothly facilitate highly regioselective and stereoselective hydrosilylation of terminal alkynes to afford beta(Z) vinylsilanes with good functional group compatibility. Furthermore, the hydride bridged dirhodium complex [Cp*Rh(mu-(SBu)-Bu-t)(mu-Cl)(mu-H)RhCp*][BF4] (5) as a potential inter-mediate was obtained by the reaction of la with excess HSiEt3.
