An efficient and convenient palladium-catalyzed C–H bond oxidative sulfenylation of indoles and related electron-rich heteroarenes with arylboronicacids and elementalsulfur has been described. This procedure provides a useful and direct approach for the assembly of a wide range of structurally diverse 3-sulfenylheteroarenes with moderate to excellent yields from simple and readily available starting

AbstractAn iodine‐catalyzed sulfenylation of free indoles with sodium sulfinates is described. The reaction selectively afforded 3‐arylthioindoles in good to high yields in anisole under metal‐free conditions. Functional groups such as halogens were well tolerated under the optimized reaction conditions.magnified image
