A novel and highly regioselective ammonium iodide-induced nonradical sulfenylation method for the construction of a C鈥揝 bond was developed via C鈥揌 functionalization. With DMSO or R1SO2NHNH2 as a sulfenylating agent, MeS- and R1S-substituted flavone derivatives were obtained in good yields. This method enriches current C鈥揝 bond formation chemistry, making it a highly valuable and practical method in pharmaceutical industry.
