A highly regioselective synthesis of branched vinylsilanes through silicon-copper additions to terminal alkynes catalyzed by copper(I) was developed using methanol as additive. The corresponding vinylsilanes were obtained with excellent branched to linear selectivity of up to 99/1 in good yields.
使用甲醇作为添加剂,开发了一种通过将硅-铜加成到由铜 (I) 催化的末端炔烃的高度区域选择性合成支化乙烯基硅烷。以高达 99/1 的优异收率获得了相应的乙烯基硅烷,具有优异的支化至线性选择性。
