A surfactant based oxodiperoxo molybdenum complex, which could activate molecular oxygen, has been employed as a catalyst for controlled oxidation of benzylic alcohols to corresponding carbonyls. The oxidation reactions were carried out under aqueous environment, however, in the absence of any extraneous base or co-catalyst. Sensitive/oxidizable functional groups like cyano, sulfide, hydroxyl, aryl-hydroxyl
基于表面活性剂的氧二过氧钼络合物可以活化分子氧,已被用作催化剂,以控制苄基醇氧化为相应的羰基。氧化反应在水性环境下进行,但是在没有任何无关的碱或助催化剂的情况下进行。在转化过程中可以耐受敏感/可氧化的官能团,例如氰基,硫化物,羟基,芳基-羟基,烯烃(内部/末端),炔烃(内部/末端)和乙缩醛。这种选择性归因于催化剂的温和性质。该方法还可以扩大规模以用于多克合成,并且该方案很可能会得到实际应用,因为它需要廉价的可回收催化剂和易于获得的氧化剂(在绿色条件下)。
