Abstract A simple and efficient method for the debromination of vic-dibromides to (E)-alkenes and reduction of sodium alkyl thiosulfates to disulfides promoted by Sm/TMSCl/H2O (trace) has been described.
A direct C2–H thiolation of azoles with Bunte salts was achieved under the combined action of copper and silver salts, furnishing various substituted 2-thioazoles in moderate to good yields.

An efficient catalytic method for the synthesis of 3-thioindoles has been successfully developed, which uses odorless, stable, readily available crystalline Buntesalts as the sulfenylating agents, iodine as nonmetallic catalyst, and DMSO as both the oxidant and solvent. This method is practical and environmentally benign in terms of sulfur sources, catalyst, and solvent. The catalytic reaction is

A novel aerobic catalytic oxidation system for the sulfenylation of indoles with a variety of sulfenylation agents through oxidative C–S bond coupling has been successfully developed. The reactions were performed with potassium iodide as the catalyst, sodium nitrite as the co-catalyst, and molecular oxygen as the terminal oxidant in the presence of acetic acid. Under the optimal reaction conditions
