systems for the selective oxidation of substituted phenol and anisole derivatives to benzoquinones is described. Environment friendly, easily available, and low cost H2O2 was used as the oxygen atom donor. All catalysts were stable systems for at least five recycling experiments. In the oxidation of some natural phenols such as cardanol derivatives higher conversion and yields of benzoquinones were
描述了一种方便有效的异质聚(4-乙烯基吡啶)/三氧化二甲基methyl(PVP / MTO)系统用于将取代的苯酚和苯甲醚衍生物选择性氧化为苯醌的方法。使用环境友好,易于获得且成本低廉的H 2 O 2作为氧原子供体。所有催化剂都是用于至少五个循环实验的稳定系统。在某些天然酚(如腰果酚衍生物)的氧化过程中,相对于均相中的MTO,观察到较高的转化率和苯醌的收率,这表明基于氢键相互作用的载体介导的分子识别过程。
