Abstract
Reactions of the coordinatively unsaturated complexes [(eta (6)-C6Me6)Ru{et a-(PrNC)-Pr-i(Me)=(NPr)-Pr-i}]X-+(-) with Me3SiCHN2 resulted in the formati on of the amidinato-carbene complexes [(eta (6)-C6Me6)Ru{=(CHNPrC)-Pr-i(Me) =N-i-Pr}(SiMe3)]X-+(-), in which a trimethylsilyl group is bonded to the ru thenium atom. Migration of the silyl group to the carbene ligand occurred o n reaction with CO, whereas the reverse reaction was promoted by photochemi cal dissociation of CO.
