A new and convenient method of generating phenyl isocyanates from anilines using oxalyl chloride is described. This reduction can also be carried out by H. When Nitro benzene is reduced electrolytically in presence of Concentrated Sulphuric acid, Phenyl hydroxylamine is first produced which rearranges to give p-Amino phenol. Why is meta nitroaniline one of the major products in nitration of aniline? NLM  |  Aniline reacts with Chloroform and alcoholic KOH to give an offensive smelling liquid, Phenyl isocyanide.
