Abstract
4-nitro benzoyl acylhydrazines are synthesized in ice bath with substituted hydrazine and 4-nitrobenzoic chloride as raw materials. At the same time ,4-nitrobenzoic acyl azo compounds are synthesized firstly with the oxidation system NBS/Pyridine. The products are characterized by elementary analysis, IR and 1HNMR, The yields of products are about from 80% to 92%.
