Abstract
The hydrosilylation of alkynes is catalyzed by the di-tert- butylphosphanylethylcyclopentadienyl-cobalt chelate 1. While the reaction of internal alkynes exclusively affords syn hydrosilylation products with triethylsilane, the reaction with triethoxysilane shows predominant anti stereoselectivity. Reactions of terminal alkynes are less selective with triethylsilane and result in cyclotrimerization when triethoxysilane is used.
