The allylic oxidation of unsaturated steroids by tert-butyl hydroperoxide using surface functionalised silica supported metal catalysts

摘要

Metal complexes based on Co(II), Cu(II), Mn(II) and V(II) immobilised on mesoporous silica, efficiently catalyse the selective allylic oxidation of unsaturated steroids and valencene, and can be easily recovered and reused.
