【Abstract】 One-pot reaction of 2-phenyl-1,2,3-triazole-4-formyl chloride with ammonium thiocyanate and acylhydrazine in the presence of polyethylene glycol-400 (PEG-400) as the PTC catalyst yielded a series of new N-(3-phenyl-2,3,4-triazole formyl)-N′-acylthiosemicarbazides. The reaction conditions were investigated. The structures of these compounds were confirmed by elemental analysis, IR and ()~1H NMR.更多还原
