【摘要】 <正>2,2,6,6-四甲基哌啶氮氧化合物是一种十分稳定的氮氧自由基,除了用作自旋标记外,它还是一种自旋催化剂。近来,自旋催化剂用于选择性催化氧化,在有机合成领域得到了广泛的应用,越来越受到人们的关注。最近我们合成了聚合物负载的自旋催化剂并用于选择催化氧化苯甲醇成苯甲醛,该催化剂显示了良好的催化性能。此外,为了探讨这种负载型催化剂的催化机理,我们对不同的自旋催化剂进行了 ESR 研究。更多还原

【Abstract】 2.2.6.6.-tetramethylpiperidinyloxy known as a stable radical is also a electron spin catalyst. Recently these spin catalysts were widely used as selective oxidation catalysts in the organic synthesis field and attracted much attention.In this paper,a novel polymer-supported spin catalyst was prepared and used as selective oxidation reagent to oxidized benzyl alcohol to benzaldehyde.The polymer-supported spin catalyst showed that excellent catalytic property.To understand the oxidation mechanism of the polymer-supported spin catalyst,the ESR of polymer-supported spin catalysts was studied.更多还原
