Abstract
Reactions of readily available N-(alkyl-, aryl-, and heteroarylsulfonyl)benzotriazoles 3a-h with
diverse nitriles, reactive heteroaromatics, alkylheteroaromatics, sulfones, and esters produced
R-cyanoalkyl sulfones 5a-i, sulfonylheteroaromatics 7a-e, R-(sulfonylalkyl)heterocycles 9a-f,
R-sulfonylalkyl sulfones 11a-g, and esters of R-sulfonyl acids 14a-c, respectively, in synthetically
useful to excellent yields. The results represent the first examples of the successful application of
sulfonylazoles for C-sulfonylation.
