Hydroboration of 1-trimethylsilyl-1-alkynes with dicyclohexylborane gives 1-trimethylsilylvinylboranes regio- and stereoselectively whose successive treatment with methyllithium, cuprous iodide and alkyl halides affords (Z)-1,2-dialkylvinylsilanes in high yields. Functionalized 1-trimethylsilyl-1-alkynes give analogous results. Successive treatment of the intermediary 1-trimethylsilylvinylboranes with
