Abstract
The oxidative ring closure reaction of some aryl-substituted thiosemicarbazones induced by “bona fide” one-electron abstracting agents was investigated, by means of both experimental and computational techniques. The corresponding 1,2,4-triazole derivatives were the only cyclization products observed. The occurrence of two slightly different mechanistic pathways for the reaction is discussed.
