摘要

3-(a-Cyanobenzylidene)-l-phenyltriazine (3a), the product of thermolysis of 5-azido-1, 4- diphenyl-1, 2, 3-triazole (2), is attacked by nucleophilic reagents at the azomethine carbon. Alcohols and phenol give rise to acetals of the N-phenylamidine of phenylglyoxylic acid (4), hydroxide produces l-benzoyl-3-phenyltriazene, and piperidine produces an azoamidine, 3- (a-piperidinobenzylidene)-l-phenyltriazene (9). Compound 3a is inert to acetic and ...
