The transition metal free catalytic hydroboration of aldehydes and ketones is very limited and has not been reported with a well-defined silicon(iv) compound. Therefore, we chose to evaluate the previously reported silicon(iv) hydride [PhC(NtBu)SiHCl], (1) as a single component catalyst and found that it catalyzes the reductive hydroboration of a range of aldehydes with pinacolborane (HBpin) under ambient conditions. In addition, compound 1 can catalyze imine hydroboration. DFT calculation was carried out to understand the mechanism.
醛和酮的无过渡金属催化硼氢化反应非常有限，并且尚未有使用结构明确的硅（IV）化合物的相关报道。因此，我们选择评估先前报道的氢化硅（IV）化合物[PhC（NtBu）SiHCl]（1）作为单一组分催化剂，发现它能在环境条件下催化一系列醛与频哪醇硼烷（HBpin）的还原硼氢化反应。此外，化合物1还能催化亚胺硼氢化反应。我们进行了密度泛函理论（DFT）计算以了解其反应机理。
