Reaction of 1-chloroalkylheterocumulenes with diphenylguanidine. Synthesis and IR spectra of 2-aryl-2-trifluoromethyl-4-oxo-6-imino- and 2-aryl-2-trifluoromethyl-4,6-diiminoperhydro-1,3,5-triazines
Abstract
1-Chloro-1-aryl-2,2,2-trifluoroethylheterocumulenes (isocyanates and carbodiimides) undergo regioselective cyclization with diphenylguanidine to give 2-aryl-2-trifluoromethyl-4-oxo-6-imino- and 2-aryl-2-trifluoromethyl-4,6-diiminoperhydro-1,3,5-triazines. An IR study of the 4-oxo-1,3,5-triazine derivatives showed a tendency for the formation of intermolecular aggregates or intramolecular hydrogen bonding, while a similar study of the 4-imino-1,3,5-triazine derivatives revealed that these compounds tend to undergo prototropic isomerization in the —NH—Ç=NPh moiety.
