Reaction of Amidrazones with Phthaloyl Chloride—Synthesis of 1,2,4‐Triazolium Salts (Part I)

Reaction of Amidrazones with Phthaloyl Chloride—Synthesis of 1,2,4‐Triazolium Salts (Part I)

Phthaloyl chloride reacts with N‐arylbenzamidrazones to give 1,2,4‐triazolium salts in very good yields. The mechanism described the products formation was discussed. The structure of the obtained products was proved by IR, mass, NMR spectra, and elemental analyses.
