Abstract
One‐pot reaction of equimolar amounts of phthaloyl chloride and N‐aryl‐benzamidrazones in the presence of two equivalents of triethylamine (Et3N), gave at r.t. 4‐aryl‐3‐(o‐carboxyphenyl)‐5‐phenyl‐1,2,4‐triazoles in good yields. The structure of the obtained products was proved by IR, mass, NMR spectra, and elemental analyses. The mechanism of product formation is discussed.
