| Abstract: | The polystyrene-supported TEMPO （TEMPO-PS） was prepared by bonding 4-hydroxyl-TEMPO on chloromethyl polystyrene surface. The TEMPO-PS/CuCl catalytic system was evaluated for aerobic selective oxidation of a range of benzyl alcohols. The results showed that the TEMPO-PS/CuCl catalytic system was effective for the transformation of a series of benzylic alcohols to the corresponding aldeyhdes under O2 atmosphere. Recycling studies showed that the catalyst can be easily recovered and reused three times without significant loss of activity. |
