摘要
报道了一个合成光导材料的单体Ｎ－乙烯咔唑的新方法，在ＫＯＨ的二甲基亚砜溶液中，用常压乙炔将咔唑乙烯化，体系中水的含量以蒸馏法控制。Ｎ－乙烯咔唑的产率达到９８％。本方法投资少，操作简便，产率高，可用于工业生产。
Abstract A new Mind of synthesis of N-vinylcar-bazole monomer was reported.The N-vinyla-tion of carbazole using acetyline was carriedout in the presence of KOH in DMSO at 145～150℃ under normal pressure. The water con-tent in the reaction svstem was controlled bydistillation,and N-vinylcarbazole was obtainedwith 98%yield.
