We developed herein an iridium-catalyzed direct C?H activation/ C?N bond formation reaction of benzenesulfonamides with sulfonyl azides. The amidation reaction provides a protocol for the synthesis of 2-aminobenzesulfonamides in good to excellent yields. This strategy features a wide substrate scope, tolerates a broad range of functional groups under external oxidant-free conditions and only releases molecular nitrogen as the sole by-product. Moreover, the preliminary mechanism was investigated and the proposed reaction pathway was provided. (Figure presented.).

Herein we report a novel rhodium-catalyzed ortho-mono-alkynylation of aryl sulfonamides. The reactions of N-tosylacetamides with triisopropylsilyl (TIPS)-substituted bromoalkyne are catalyzed by a [(Cp?RhCl2)2] complex without cyclization, forming ortho-(
