The first electrochemical hydrolysis of hydrosilanes to silanols under mild and neutral reaction conditions is reported. The practical protocol employs commercially available and cheap NHPI as a hydrogen‐atom transfer (HAT) mediator and operates at room temperature with high selectivity, leading to various valuable silanols in moderate to good yields. Notably, this electrochemical method exhibits a
据报道,在温和和中性的反应条件下,氢化硅烷首次电化学水解为硅烷醇。该实用方案使用可商购的廉价NHPI作为氢原子转移(HAT)介体,并在室温下以高选择性运行,从而以中等至良好的收率生产出各种有价值的硅烷醇。值得注意的是,这种电化学方法具有广泛的底物范围和较高的官能团相容性,适用于复杂分子的后期官能化。初步的机理研究表明,该反应似乎是通过电产生的甲硅烷基阳离子与H 2 O的亲核取代反应进行的。
