以Mn(Ⅲ)/Mn(Ⅱ)为间接氧化还原体系,用间接电氧化的方法,在相转移催化条件下对醇类的氧化进行了研究。结果表明,在所用实验条件下,Mn(Ⅲ)可以方便地在电极上生成及再生,对苄醇类及二级脂肪醇类能高产率地选择性氧化成相应的羰基化合物。
Oxidation of alcohols was investigated by indirect electroxidation with phase transfer catalysis using Mn (Ⅲ) / Mn (Ⅱ) as an indirect redox system. The results show that under the experimental conditions, Mn (Ⅲ) can be easily generated and regenerated on the electrode, and the benzylic alcohols and the secondary aliphatic alcohols can be selectively oxidized to the corresponding carbonyl compounds with high yield.
