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-(1-alkynyl) benzenesulfonamides. While triethylsilyl or trimethylsilyl (TES or TMS)-substituted bromoalkyne was also amenable to the alkynylation, affording six-membered
