triphenyl-2-phenylvinylphosphonium bromide, methyldiphenyl-2-phenylvinylphosphonium bromide, and halomethyltriphenylphosphonium halides are accompanied by phenyl migration from phosphorus to adjacent carbon. It is suggested that this migration is explained by the presence on the α-carbon atom of an electron-delocalizing substituent or a good leaving group.
Buta-1,3-dien-1-基三苯基tri溴化物,三苯基-2-苯基乙烯基bro溴化物,甲基二苯基-2-苯基乙烯基yl溴化物和卤代甲基三苯基phosph卤化物的碱水解伴随有苯基从磷向相邻碳的迁移。建议通过电子离域取代基或良好的离去基团在α-碳原子上的存在来解释这种迁移。
