STUDY OF NITRATION OF N,N′-DISUBSTITUTED HYDRAZINES

The nitration of N, N′-disubstituted hydrazines (RNH-NHR) by means of nitric acid - acetic anhydride mixtures has been found to yield, in most cases, the azo derivatives (RN = NR). For example, when R = CH 3 , (CH 3 ) 2 (CN)C, CH 3 CO, or C 2 H 5 OCO, azo derivatives were formed. When R = HCO, nitrogen, carbon dioxide, and nitrogen oxides were evolved. An exception was observed with N, N′-dibenzoylhydrazine which, under the same conditions, yielded the N, N′-dinitro-N, N′-dibenzoylhydrazine.
