摘　　要：Six diaryl acylhydrazine compounds were synthesized in normal temperature with self-made acyl-diazene compounds as raw materials and NH2NH2·H2O as reducer.The products were confirmed by means of elemental analysis,IR and 1H NMR.In the results of IR,there were two N-H absorption at approximately 3200 and 3400 cm-1.However,the absorptions of N=N in raw materials disappeared.In the results of 1H NMR,the N-H chemical shifts couldn’t be found.Meanwhile,two N-H chemical shifts were detected about from 8.46 to 11.38,respectively.The results of products’ elemental analysis were consistent with the theoretical values.The yields of those six products were about from 84% to 93%.Six diaryl acylhydrazine compounds were synthesized in normal temperature with self-made acyl-diazene compounds as raw materials and NH2NH2 · H2O as reducer.
