Abstract

Abstract tert-Alkyl sulfides, with an α-(1H-benzotriazol-1-yl) group 6 and 13, are readily prepared from N-[(aryl-thio) methyl]-1H-benzotriazoles 3 and N-(11), respectively, by reaction with BuLi and then with the appropriate electrophile. The tert-alkyl sulfides 6 and 13 are smoothly converted by BF 3. OEt 2 into vinyl sulfides 5, 7 or 12, respectively, in satisfactory yields.
