VO(acac)(2) supported on titania: a heterogeneous protocol for the selective oxidation of sulfides using TBHP
The facile catalytic oxidation of sulfides to sulfoxides has been achieved with VO(acac)(2) supported on titania using tert-butyl hydroperoxide (TBHP) as an oxidant in dichloromethane in quantitative yields at room temperature. The catalyst is reusable and tested for five cycles without significant loss of activity and selectivity.
