摘　　要：Hydromagnesiation of silylarylacetylenes 1 in diethyl ether gave （E）-β-silylvinyl Grignard reagents 2, which reacted with trialkylstannyl chlorides 3 to afford stereoselectively （E）-β-silylvinylstannanes 4 in good yields.Hydromagnesiation of silylarylacetylenes 1 in diethyl ether gave （E）-β-silylvinyl Grignard reagents 2, which reacted with trialkylstannyl chlorides 3 to afford stereoselectively （E）-β-silylvinylstannanes 4 in good yields.
