It was found that oxidation potentials of methanes with π-electron substituents were decreased by introduction of a trimethylsilyl group. The anodic oxidation of benzyl-, allyl-, aryl(or alkyl)thiomethyl-, and aryloxymethyl-substituted trimethylsilanes smoothly proceeded in the presence of nucleophiles, e.g. alcohols and carboxylic acids, to eliminate the trimethylsilyl groups giving the corresponding
发现通过引入三甲基甲硅烷基,具有 π 电子取代基的甲烷的氧化电位降低。苄基-、烯丙基-、芳基(或烷基)硫代甲基-和芳氧基甲基-取代的三甲基硅烷的阳极氧化在亲核试剂(例如醇和羧酸)的存在下顺利进行,以消除三甲基甲硅烷基,得到相应的烷氧基化和羧化产物。在没有充分优化电解条件的情况下获得中等或高产率,而氨基甲基硅烷没有经历这种阳极氧化。
