A copper-catalyzed regioselective sulfenylation of indoles and a pyrrolo[ 2,3-b]pyridine with arylsulfonyl chlorides has been developed by using low loadings of a copper catalyst and the cheap reductant PPh3. This method is effective for both N-protected and unprotected indoles, providing a series of structurally diverse indole thioethers in good to excellent yields with extremely high regioselectivity.
