A controlled aerobic oxidation of primary benzylic alcohols to the corresponding benzaldehydes by using polystyrene–poly(ethylene glycol) (PS–PEG) resin-supported triazine-based polyethyleneamine dendrimer–copper complexes [PS–PEG-TD2–Cu(II)] was developed. In particular, PS–PEG-TD2–Cu(OAc) 2 efficiently catalyzed the aerobic oxidation of benzylic alcohols in the presence of a catalytic amount of TEMPO under atmospheric conditions to give the corresponding aldehydes in up to quantitative yield. The catalyst was readily recovered by simple filtration and reused four times without significant loss of its catalytic activity.

聚合物负载的三嗪基树枝状大分子-铜复合材料催化伯苯甲醇受控有氧氧化成醛
通过使用聚苯乙烯-聚（乙二醇）（PS-PEG）树脂负载的三嗪基聚乙烯胺树枝状大分子-铜配合物[PS-PEG-TD2-Cu(II)]，将伯苯甲醇受控有氧氧化为相应的苯甲醛。发达。特别是，PS-PEG-TD2-Cu(OAc) 2 在催化量的 TEMPO 存在下，在大气条件下有效催化苯甲醇的有氧氧化，以达到定量收率得到相应的醛。该催化剂通过简单的过滤很容易回收并重复使用四次而其催化活性没有显着损失。
