Yh. Kang et K. Kim, OXIDATION OF 1-[(ARYL)(PHENYISELENO)METHYL]BENZOTRIAZOLE, ARYL)(ARYLTHIO)(PHENYLSELENO)METHYL]BENZOTRIAZOLE, AND 1-[(ARYL)(DIPHENYLSELENO)METHYL]BENZOTRIAZOLE WITH M-CHLOROPERBENZOIC ACID, Journal of heterocyclic chemistry, 34(6), 1997, pp. 1741-1752
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 su
lfones and sulfoxides by treatment with m-chloroperbenzoic acid (m-CPB
A) and sodium periodate, respectively. No compounds derived from a het
erolytic cleavage between the alpha-carbon and the N-1 atoms of the fo
regoing compounds were isolated.
