研究了5 种助催化剂对甲基二氯硅烷与氯丙稀加成反应的影响.发现γN,N二乙基氨丙基三乙氧基硅烷和三乙胺助催化效果较好,可大大地缩短反应诱导期,在2.5h 内即可完成反应. The effects of five kinds of cocatalysts on the addition reaction of methyldichlorosilane and chlorpropenone were studied and it was found that γN, NDIMA and triethylamine promoted the co- Can greatly shorten the induction period, within 2.5h to complete the reaction.
