A palladium‐catalyzedα‐arylation of sulfonamides with aryl chlorides is presented. A Buchwald‐type pre‐catalyst formed with Kwong’s indole‐based ligand enabled this transformation to be compatible with a large variety of methyl sulfonamides and aryl chlorides in good to excellent yields. Importantly, under the optimized reaction conditions, only mono‐arylated products were observed. This method has
