W. Zielinski et W. Czardybon, Synthesis of 3,5-diaryl-4-benzyledeneamino-1,2,4-triazoles and 4-amino-3,5-diaryl-1,2,4-triazoles, KHIM GETERO, (9), 2001, pp. 1207-1210
A one pot reaction leading to 3,5-diaryl-4-benzylideneamino-1,2,4-triazoles
is described, the key step of which is the reaction of arenecarbohydrazono
yl chloride with benzylidenehydrazide. Compounds obtained in this way were
hydrolyzed to 4-amino-3,5-diaryl-1,2,4-triazoles.
