operationally simple transformation proceeds under mild conditions without external ligands and features high catalytic efficacy and good functional-group tolerance. Furthermore, the generality of this developed catalytic system was further demonstrated by the late-stage modification of bioactive molecules.
在此,我们报道了以 Ph 2 SiH 2或廉价的聚甲基氢硅氧烷 (PMHS) 作为还原剂,通过 [Mn(CO) 5 Br] 使仲胺和叔胺脱氧,从而方便地获得相应的仲胺和叔胺。操作简单的转化在没有外部配体的温和条件下进行,具有高催化效率和良好的官能团耐受性。此外,生物活性分子的后期修饰进一步证明了这种开发的催化系统的通用性。
