硅烯是有机合成中一类基本的反应活性中间体。从六十年代起,许多有机化学家曾用热化学方法或光化学方法获得了二甲基硅烯、甲基苯基硅烯、苯基三甲硅基硅烯等。最近我们也报道了二苯基硅烯的生成。硅烯的亲电性很强,能和碳-碳双键、叁键等发生加成反应,并对C—H,Si—H,Si—O,Si—X等化学键发生插入反应。通过二甲基硅烯和二苯基 Silylene is a class of basic reactive intermediates in organic synthesis. Since the 1960s, many organic chemists have obtained dimethylsilylene, methylphenylsiloxane, phenyltrimethylsilylene and the like thermally or photochemically. We have also recently reported the formation of diphenylsilylene. Silicone electrophilic strong, and carbon-carbon double bond, triple bond addition reaction occurred, and the C-H, Si-H, Si-O, Si-X and other chemical bonds inserted reaction. Through dimethylsilylene and diphenyl
