A novel electrochemical system for sulfenylation of indoles with disulfides to generate 3-sulfenylindoles via C-S bond formation mediated by potassium iodide at a low potential was developed. Iodine was electrogenerated from iodide ions at a graphite anode and showed a high catalytic activity for the electrochemical sulfenylation reactions. A variety of aromatic, heteroaromatic and aliphatic disulfides could react with 2-methlyindole to synthesize the corresponding 3-sulfenylindoles in good to excellent yields. In addition, protected and unprotected indoles with various groups, especially electron-donating groups, also performed well in the sulfenylation reactions. The transformation, which proceeded through the redox of iodine and the generation of intermediate 3-iodoindole, provided an efficient and environmentally benign protocol for the synthesis of 3-sulfenylindoles under mild conditions.

An efficient metal-free sulfenylation of indoles with disulfides has been developed, leading to 3-arylthioindoles in moderate to excellent yields. Furthermore, bromosulfenylation of indoles with disulfides has been realized for the first time providing a

Selective sulfenylation of indoles with disulfides using iron(III) fluoride combined with iodine has been developed for the synthesis of sulfenylindoles. In the presence of iron(III) fluoride and iodine, a variety of disulfides underwent the reaction with indoles selectively to afford the corresponding sulfenylindoles in good to excellent yields. Moreover, reactions of indoles with 1,2-diphenyldiselane were also conducted under the same conditions, which smoothly afforded 3-selenylindoles in good yields.
