Abstract
AbstractCumyl hydroperoxide (CHP) and tert‐butyl hydroperoxide (TBHP) produced (R)‐ and (S)‐sulfoxide in 2,10‐camphanediol‐titanium catalyzed sulfoxidation, respectively. During kinetic resolution, the sulfoxide configuration was reversed with CHP, but kept with TBHP. Based on these results and the ESI‐MS data, the mechanism of sulfoxidation was proposed to be intramolecular nucleophilic oxygen transfer to a coordinated sulfide.
