Abstract
To suppress the over-oxidation of solvents, reaction conditions were optimized, and ligands were added to the system to facilitate the oxidation of sulfur compounds with molecular oxygen. The addition of suitable nitrogen ligands led to effective suppression, and 2,2′-bipyridine showed the best performance among the analyzed samples. After the use of the ligand, the yields of by-products from solvent oxidation were reduced by a factor of 15 compared to those from the reaction without any ligands.
