摘要
将4-羟基-TEMPO通过醚键负载于聚苯乙烯氯球上制得负载TEMPO氯球(TEMPO-PS),考察了TEMPO-PS/CuCl体系催化苄醇选择性氧气氧化的性能。结果表明,在离子液体[bmi m][PF6]中,TEMPO-PS/CuCl体系对各种苄醇均有较好的催化活性。催化体系经3次循环使用活性无明显降低。
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.
