Electrochemical sulfenylation of indoles with disulfides mediated by potassium iodide

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.

A tetra-: N -butylammonium iodide mediated reaction of indoles with Bunte salts: Efficient 3-sulfenylation of indoles under metal-free and oxidant-free conditions

A highly efficient tetra-n-butylammonium iodide (TBAI) triggered procedure for 3-sulfenylation of indoles with Bunte salts is demonstrated. This protocol provides a simple strategy to prepare 3-alkylthioindoles and 3-arylthioindoles from the corresponding indoles under metal-free and oxidant-free conditions.

Iron(III) chloride: A versatile catalyst for the practical synthesis of 3-sulfenylindoles

The direct sulfenylation of indoles with aromatic thiols has been accomplished in the presence of 20 mol% of FeCl3 in refluxing acetonitrile to produce 3-arylthioindoles in relatively good to excellent yields and with high selectivity. This met
