A facile method to 1,4-diacyl semicarbazides: Syntheses of 1-aryloxyacetyl-4-(4-chlorobenzoyl)-thiosemicarbazides and semicarbazides

Wang, Xicun,Li, Zheng,Da, Yuxia,Chen, Jichou

, p. 3405 - 3411 (2007/10/03)

A facile method to diacyl semicarbazides is described. Reactions of 4-chlorobenzoyl chloride with ammonium thiocyanate first, then with aryloxyacetic acid hydrazides under phase transfer catalysis give 1-aryloxyacetyl-4-(4-chlorobenzoyl)-thiosemicarbazide
