Convenient sulfonylation of imidazoles and triazoles using NFSI

A protocol for the synthesis of N-sulfonyl imidazoles and triazoles has been achieved using N-Fluorobenzenesulfonimide as a sulfonyl source. This reaction proceeded well in the absence of strong bases and catalysts, providing a convenient alternative method for the preparation of N-sulfonyl imidazoles as well as triazoles.

Iodine-catalyzed N-sulfonylation of benzotriazoles with sodium sulfinates under mild conditions

A new and convenient procedure is developed for the preparation of N-sulfonylbenzotriazoles from sodium sulfinates and benzotriazoles using molecular iodine as catalyst via the S[sbnd]N bond formation reaction. This catalytic radical sulfonylation proceed

Convenient sulfonylation of benzotriazoles with the in situ–generated sulfonyl bromides

A convenient procedure is developed for the preparation of N-sulfonylbenzotriazoles from sodium sulfinates, benzotriazoles, and sodium bromide in the present of m-chloroperbenzoic acid as oxidant. This radical sulfonylation proceeds efficiently at room te
