Phase-transfer catalyzed mild synthesis of 1,5-diacyl thiocarbohydrazides and their solventless expeditious transformation to 1,5-diacyl carbohydrazides

Li, Zheng,Zhao, Yanlong,Yang, Jingya

, p. 79 - 84 (2007/10/03)

1,5-diacyl thiocarbohydrazides were efficiently synthesized by the reactions of thiocarbohydrazide with a variety of aroyl chlorides at r.t. using PEG-400 as a phase-transfer catalyst. Meanwhile, 1,5-diacyl thiocarbohydrazides were be expeditiously transf
