摘要：

The yellow, coordinatively unsaturated silyl thiocarbonyl complexes of ruthenium and osmiuM M-(SiMe2Cl)CI(CSXPPh3)2 (M = Ru (1a), Os (2a)) can be prepared by reaction of HSiMe2Cl with MHCI(CSXPPh3)3 or MPhCl(CSXPPh3)2. The Si-Cl bond in la and 2a is readily cleaved by ethanol, and the corresponding ethoxysilyl complexes 1b and 2b are formed. Addition of CO to la, lb, and 2b induces an immediate migratory insertion reaction involving the silyl and thiocarbonyl ligands, and the novel eta2-Silathioacyl complexes M(eta2-C[S]-SiMe2X)Cl(COXPPh3)2 (M = Ru, X = OEt (1c), Cl (1d); M = Os, X = OEt (2c)) are formed. The single-crystal X-ray structure determination of 1c is described.
