【Abstract】 A new one pot preparation of 4 amino 5 phenyl 1,2,4 triazole 3 thione is described by using benzolyl hydrazine which was prepared by esterification and hydrazinolysis of benzoic acid,carbon disulfide and hydrazine hydrate as starting substrates. This method is featured by shorter processing time,lower costing and higher productivity. The product purity is 95%(GC),yield is 51.2%.更多还原
