Abstract

Abstract 3-Hydrazino-5, 6-diphenyl-1, 2, 4-triazine reacts with 4-arylidene-2-phenyl-5 (4H)- oxazolones in toluene to give substituted acrylic acid hydrazides, and in glacial acetic acid to give substituted imidazolones. On the other hand the hydrazinotriazine reacts with 4- benzylidene-3-methyl-5 (4H)-isoxazolone, probably via a 1, 4 addition reaction followed by an elimination reaction, to give benzaldehyde 5, 6-diphenyl-1, 2, 4-triazin-3-ylhydrazone ...
