Autor: S.V. Vinogradova, Korshak Vasilij, V. A. Pankratov, N. P. Antsiferova, D. F. Kutepov

Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 22:1371-1373

1. Depending on the cyclotrimerization conditions, phenylcyanamide forms two isomeric forms of triphenylmelamine. 2. At temperatures above its melting point, triphenylisomelamine is isomerized to the normal structure, namely 2,4,6-triphenylamino-1,3,
