A highly versatile and efficient hydrosilylation method by palladium nanoparticle catalysis allows the direct and chemoselective synthesis of 1) enolsilanes of high isomeric purity, 2) saturated aldehydes or ketones, or 3) the corresponding saturated acetals from α,β‐unsaturated aldehydes or ketones. The choice of the product is determined by simply switching the solvent from THF to mixtures of THF/water
通过钯纳米粒子催化的高度通用和高效的氢化硅烷化方法可以直接和化学选择性地合成1)高异构纯度的烯醇硅烷,2)饱和醛或酮或3)由α,β-不饱和醛或酮相应的饱和缩醛。通过简单地将溶剂从THF切换为THF /水或THF /醇的混合物来确定产品的选择。
