Hydroxyapatite‐supported gold nanoparticles (Au/HAP) can act as a highly active and reusable catalyst for the coupling of hydrosilanes with amines under mild conditions. Various silylamines can be selectively obtained from diverse combinations of equimolar amounts of hydrosilanes with amines including less reactive bulky hydrosilanes. This study also highlights the applicability of Au/HAP to the selective
羟基磷灰石负载的金纳米颗粒(Au / HAP)在温和的条件下可充当高活性和可重复使用的催化剂,用于氢化硅烷与胺的偶联。可以从等摩尔量的氢硅烷与胺(包括反应性较小的笨重的氢硅烷)的各种组合中选择性地获得各种甲硅烷基胺。这项研究还强调了Au / HAP通过氢硅烷与酰胺的偶联选择性合成甲硅烷基酰胺的适用性,证明了高效多相催化剂的第一个实例。此外,Au / HAP在克级合成中显示出很高的可重用性和适用性。
