3-bromo-2-trimethylsilyl-1-propene 1c reacts with various electrophiles (aldehydes, a ketone, nitriles, terminal alkynes) in the presence of zinc to give functionnalized vinylsilanes. A three steps synthesis of 2-substituted-4-trimethylsilylfurans from 1c and a nitrile is described. Opening of epoxysilanes with cuprates gave an easy access to α-trimethylsilyl-alcohols.
3-溴-2-三甲基甲硅烷基-1-丙烯1c在锌的存在下与各种亲电试剂(醛,酮,腈,末端炔烃)反应,生成官能化的乙烯基硅烷。描述了由1c和腈合成三步2-取代的4-三甲基甲硅烷基呋喃的步骤。用铜酸盐打开环氧硅烷使得容易获得α-三甲基甲硅烷基醇。
