3‐Hydrazino‐5,6‐diphenyl‐1,2,4‐triazine reacts with 4‐arylidene‐2‐phenyl‐5(4 H )‐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(4 H )‐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 and 3‐methyl‐5(4 H )‐isoxazolone.
