Reaction of benzoyl and trichloroacetyl isocyanates with Schiff bases

Conclusions Benzalbenzylamine and p-substituted benzalbenzylamines react with benzoyl and trichloroacetyl isocyanates by the type of 1,4-addition, with the formation of 2,6-diphenyl-3-benzyl-3,4-dihydro-2H-1-oxa-3, 5-diazin-4-one and 2-phenyl-3-benzyl-6-trichloromethyl3,4-dihydro-2H-1-oxa-3,5-diazin-4-one derivatives.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 617–621, March, 1970.
