Sarkate, A. P. published the artcileMicrowave-Assisted Copper Slag-Catalyzed Green S-Arylation of Arenethiols with Arylboronic Acids, Synthetic Route of 197958-29-5, the publication is Russian Journal of Organic Chemistry, database is CAplus.
Diaryl sulfides have been synthesized in moderate to excellent yield by S-arylation of arenethiols with arylboronic acids using copper slag as a catalyst. Copper slag is a byproduct obtained from smelting and refining of copper. Conventional heating method has been compared with the microwave-assisted technique. The proposed microwave-assisted synthesis provides excellent yields of diaryl sulfides ArSAr1 (Ar = Ph, 4-HOC6H4, 2-pyridyl, etc.; Ar1 = Ph, 4-MeOC6H4) in a short time (10 min) and is ligand-free, green, and cost-effective.
