A simple and convenient method has been developed for the construction of 3-thioindoles via molecular iodine-catalyzed direct thiolation of indoles with thiols. The present protocol, which employs thiols as the thiolating agents, inexpensive molecular iodine as the catalyst, and environmentally benign air as the oxidant, allows the regioselective generation of 3-thioindoles in good to excellent yields
