摘要：

We describe a bis-N-heterocyclic carbene rhodium(III) complex, featuring two trifluoroacetato ligands, that affords a variety of alpha-vinylsilanes in good yields by hydrosilylation of terminal alkynes. Selectivities around 7: 1 alpha/beta-(E) were reached, while the beta-(Z) product was only marginally obtained. This example sharply contrasts with the beta-(Z)-selectivity observed for its parent diiodido complex
