Hydrochloric Acid → N-Nitrosodiphenylamine

참여 물질

반응 단계

The compound 1,1-diphenylhydrazine is commercially available. The substituted 1,1-diphenylhydrazines can be made by reacting the corresponding 1,1-diarylamine with sodium nitrite and hydrochloric acid in dimethylformamide at about 10° C. to produce an N-nitrosodiphenylamine, then adding the N-nitroso compound in tetrahydrofuran to a suspension of lithium aluminum hydride in dry ether under nitrogen and maintaining the temperature at 25°-35° C. for about 11/2 hours. The procedure is analogous to that given for preparation of N-amino-iminodibenzyl in Cohen et al., U.S. Pat. No. 3,457,271.
