catalyst for the oxidative synthesis of benzoxazoles in the gram-scale from phenolic imines at room temperature. H2O2 and biobased reagent dimethyl carbonate (DMC) were successfully employed as the environmentally friendly oxidant and solvent, respectively, in an OMS-2-catalysted redox reaction for the first time. Benzoxazoles could also be obtained from N-substituted 2-aminophenols via Cu(OH)x/OMS-2-catalyzed
锰八面体分子筛(OMS-2)被发现是一种高效且可回收的异构催化剂,用于在室温下以克为单位从酚亚胺氧化合成苯并恶唑。H 2 O 2和生物基试剂碳酸二甲酯(DMC)分别成功地首次在OMS-2催化的氧化还原反应中用作环境友好型氧化剂和溶剂。苯并恶唑还可以在高温下通过Cu(OH)x / OMS-2-催化的连续氧化转化反应从N-取代的2-氨基苯酚获得。
