Synthesis of Oxamic Acids Thiohydrazides and Carbamoyl-1,3,4-thiadiazoles
摘要:
A convenient preparation method was developed for oxamic acids thiohydrazides by reaction of alpha-chloroacetamides with a preliminary prepared solution of elemental sulfur and hydrazines. A series of carbamoyl-1,3,4-thiadiazole derivatives was obtained.
