Reaction of ammeline and aromatic amine hydrochloride by fusion yielded 72% N, N'-diphenylammeline, mp 370-1°c (d) (molar ratio 1: 4, 250°c, 15 min); 32% N, N'-di-o-toluylammeline, mp 360-1°c (d) (molar ratio 1: 4, 240°c, 2 hr); 64% N, N'-di-m-toluylammeline, mp 342-3°c (d) (molar ratio 1: 5, 245°c, 15 min); 88% N, N'-di-p-toluylammeline, mp 364-5°c (d) (molar ratio 1: 4, 250°c, 20 mm). This reaction has not been known. Since N, N'-diarylureas are obtainable as by-products, these are assumed to be derived from decomposition by opening of s-triazine ring. The chemical structures of the product of this reaction were confirmed from determination of mixed mp. with N, N'-diarylammeline obtained by hydrolysis of 2, 4-bisarylamino-6-chloro-s-triazines and N, N'-diarylurea obtained by arylation of urea.
