tolyl-derivatives. This is achieved by an organosilane-mediated ester hydrosilylation reaction and subsequent Ni/NHC catalyzed hydrogenolysis. The resulting conditions provide a direct and efficient alternative to multi-step procedures for this transformation that often require use of hazardous metal hydrides. Applications in the synthesis of -CD3 containing products, derivatization of bioactive molecules, and chemoselective
我们报告了将未活化的芳基酯直接还原为其相应的甲苯基衍生物的一步程序。这是通过有机硅烷介导的酯氢化硅烷化反应和随后的 Ni/NHC 催化氢解来实现的。由此产生的条件为通常需要使用危险金属氢化物的这种转化的多步骤程序提供了一种直接有效的替代方法。展示了在合成含 -CD3 的产品、生物活性分子的衍生化以及在其他 CO 键存在下进行化学选择性还原中的应用。
