Abstract
4-nitro benzoyl acylhydrazines were synthesized in ice bath with substituted hydrazine and 4-nitrobenzoic chloride as raw materials.At the same time,4-nitrobenzoic acyl azo compounds were synthesized firstly with the oxidation system NaBrO3/H2SO4.The products were characterized by elementary analysis,IR and 1HNMR.The yields of products were about from 84% to 93%.
