Decomposition of N‐aroyl‐O‐arylcarbamoyl‐hydroxylamines VII —N‐(1‐ 14 C) benzoyl‐O‐phenylcarbamoyl‐hydroxylamine ( 1y ). N‐(p‐toluyl)‐O‐phenylcarbamoyl‐hydroxylamine ( 4 ) and N‐Benzoyl‐O‐(p‐tolyl) carbamoyl‐hydroxylamine ( 5 ) — in various systems yields arylhydroxamic acids X and N, N′‐diarylurea‐mixtures VI / XII / XIII , what is explained by two reaction paths. The reaction of 1y with aniline or p‐toluidine to unlabelled N,N′‐diphenylurea or N‐phenyl‐N′‐(p‐tolyl) urea is showing that the diarylurea is formed from the amine and the phenylcarbamoyl group of 1y .
