The reactions of bis (trimethylsilyl) peroxide with alkyl, vinyl, alkynyl, aromatic and heteroaromatic anions are described. Depending on the reaction conditions, the trimethylsilyloxy derivatives can be obtained alone or together with the corresponding trimethylsilyl derivatives, which is sometimes the major product. Enolates, generated using magnesium diisopropylamide give the corresponding hydroxycarbonyl
描述了双(三甲基甲硅烷基)过氧化物与烷基,乙烯基,炔基,芳族和杂芳族阴离子的反应。取决于反应条件,三甲基甲硅烷基氧基衍生物可以单独获得或与相应的三甲基甲硅烷基衍生物一起获得,其有时是主要产物。使用二异丙基酰胺镁生成的烯醇化物以良好的收率得到相应的羟基羰基化合物。给出合理化上述结果的尝试,强调了双(三甲基甲硅烷基)过氧化物在有机合成中作为亲电子羟基化试剂的广泛应用。
