In this study, the direct copper-catalyzed C—S coupling reaction of heterocyclic compounds with diphenyl disulfide, without the existence of ligands and alkalis, has been developed. It showed that the yield of target product was 89.9% when the reaction was carried out at 110 ℃, the reaction time was 12 h, dimethylsulfoxide (DMSO) was used as solvents, and the molar ratio of heterocyclic compound to biphenyl disulfide was 2:1. The structures of the target products were confirmed with 1H NMR and 13C NMR. The effects of various conditions on the reaction were investigated by high performance liquid chromatography (HPLC) analysis and its reaction mechanism was discussed.

Key words: aryl thioether, benzo heterocyclic compounds, diphenyl disulfide, HPLC
