摘要
乙基溴化镁与末端炔烃反应生成炔基Grignard试剂,后者分别与三甲基氯化硅和三丁基氯化锡反应,高产率地合成了相应的炔基硅烷和炔基锡烷,提供了合成炔基硅烷和炔基锡烷的简便方法.
The alkynylmagnesium bromides can be successfully prepared by the reaction of ethylmagnesium bromide and terminal alkynes in THF. Subsequent reactions with chlorotrimethylsilane and chlorotributylstannane give the expected alkynylsilanes and alkynylstannanes in good yields,which provides a novel procedure for the preparation of alkynylsilanes and alkynylstannanes. Compared to the reported methods, the present method for the preparation of alkynylsilanes and alkynylstannanes has the advantages of readily available and cheap starting materials, simple procedures and high yields.
