Abstract

[Co(IAd)(PPh₃)(CH₂TMS)] exhibits high catalytic efficiency and selectivity as well as good functional group compatibility in alkyne hydrosilylation. Regio- and stereoselective hydrosilylations of terminal, symmetrical internal, and trimethylsilyl-substituted unsymmetrical internal alkynes provide β-(E)-silylalkenes, (E)-silylalkenes, and (Z)-α,α-disilylalkenes, respectively, in high yields.
