Selective Monodesulfonylation of N,N-Disulfonylarylamines with Tetrabutylammonium Fluoride.

Abstract

The monodesulfonylation reaction of N, N-bis(methylsulfonyl)-, N, N-bis(phenylsulfonyl)-, and N, N-bis(p-tolysulfonyl)arylamines easily proceeded using tetrabutylammonium fluoride in tetrahydrofuran under mild conditions to give the corresponding N-monosulfonylarylamines in excellent yields.
