Abstract
Abstract The reaction of 1,1-diphenylhydrazine with chloroform in the presence of potassium hydroxide gives diphenylamine as the major product and not benzophenone as originally reported. This seems to be the favored path regardless of the source of dichlorocarbene. Diphenylcyanamide (but not the isomeric isonitrile) was identified in trace amounts. The reaction of phenylhydrazine under similar conditions has been also reinvestigated and gave N,N′-diphenylformazan; aniline and phenyl isonitrile have also been identified. A mechanism for the rationalization of these results is presented.
