Electrochemical synthesis of 2-aryl-2H-benzotriazoles and their N-oxides by controlled potential cathodic electrolysis

Using a divided cell, reductive cyclizations of o-nitrophenylazo dyes (1) toward 2-aryl-2H-benzotriazole-1-oxides (2) or 2-aryl-2H-benzotriazoles (3) were successfully accomplished by the controlled potential cathodic electrolysis reactions. 1 was transformed to 2 under neutral conditions while 1 was transformed to 3 under basic conditions.

Photooxidation of 2-Phenylbenzotriazoles

Irradiation, with ultraviolet light, of 2-phenylbenzotriazole in aerated solvents resulted in oxidation of the benzo ring to yield the diacid 2-phenyl-1,2,3-tiazole-4,5-dicarboxylic acid.A possible intermediate, 2-phenylbenzotriazole-4,7-dione, also yielded the diacid on photooxidation.The methyl ether of the commercial photostabilizer Tinuvin P undergoes an analogous reaction to produce the corresponding diacid.
