A simple method for the preparation of silanols from the corresponding hydrosilanes is reported. The method employs a commercially available oxidizing system based on CuCO3/t-BuOOH(aq) under relatively mild conditions (80 °C, atmospheric pressure) with acetonitrile as the solvent. Furthermore, we present a method that permits the Si−H group to be oxidized to a Si−OH group not only in triethylsilane, but also in bis(trimethylsiloxy)methylsilane, a siloxy derivative of hydrosilane. The products were isolated in gram amounts in yields of 61–73%.

铜催化氧化氢硅烷:合成烷基和甲硅烷氧基硅烷醇的新方法

报道了一种从相应的氢硅烷制备硅烷醇的简单方法。该方法采用基于 CuCO3/t-BuOOH(aq) 的市售氧化系统,在相对温和的条件下(80 °C,大气压),以乙腈为溶剂。此外,我们提出了一种方法,不仅在三乙基硅烷中,而且在双(三甲基甲硅烷氧基)甲基硅烷(氢硅烷的甲硅烷氧基衍生物)中,Si-H 基团也可以被氧化为 Si-OH 基团。产物以克量分离,产率为 61-73%。
