We report a coupling reaction of thioamides and sulfonyl azides to generate sulfonyl amidines in the absence of any activation additives. The reaction progresses in various solvents under mild conditions. Water exhibits the highest performance with respect to efficiency.

N-sulfonyl amidine compounds through three-component reaction of aryl diazonium salts with sulfonamides and acetonitrile, in which, nitrilium ion intermediate, generated from the reaction of aryldiazonium salt with nitrile, was subsequently trapped by sulfonamides. A series of N-sulfonyl amidine derivatives were synthesized by using various types of aryl diazonium salts, sulfonamides and nitriles. In addition
