During the last decade, benzotriazole (1) has received much attention as an excellent synthetic auxiliary [1]. Recently Katritzky, et al. [2] studied the oxidation of 1-(phenylthiomethyl)benzotriazole (2a) and 1-(2-phenyl-1-phenylthioethyl)benzotriazole (2b) and obtained their sulfones and sulfoxides by treatment with m-chloroperbenzoic acid (m-CPBA) and sodium periodate, respectively. No compounds derived from a heterolytic cleavage between the α-carbon and the N-1 atoms of the foregoing compounds were isolated.
