The oxidative cyclization of formazans to tetrazolium salts. Bromine oxidizes 1,3,5- triarylformazans (1) quantitatively to the corresponding 2,3,5- triaryltetrazolium salts (2) in methanol or aqueous acetic acid. The reaction is ionic and is markedly aided by electron donation in the aryl rings. In methanol containing 0. A mechanism of oxidation is proposed involving electrophilic attack by bromine at carbon and formation of a covalent intermediate, followed by unimolecular C.
