β¦ Synopsis
Selective oxidation of sulfides to sulfoxides is achieved using H 2 O 2 and TMSCl as the promotor. Aromatic and aliphatic sulfides are oxidized to sulfoxides in excellent yields and in short reaction times. Different functional groups including ketone, alkene, ester, and alcohol are tolerated.

In situ prepared manganese complexes with ligands 1-5 have been used in the catalytic oxidation of sulfides to sulfoxides using hydrogen peroxide at 0Β°C in acetone. Using ligand 4, methyl phenyl sulfoxide is obtained in 55% yield and turnover numbers up to 250, while the formation of sulfone is almo
