In this study, ruthenium(II)-catalyzed direct hydrosilylation of internal alkynes with high regio-selectivity and stereo-selectivity is reported. This title transformation led to various vinylsilanes in good to excellent yields. This approach features mild reaction conditions, low catalyst loading, air-stability, and good functional group tolerance. Furthermore, gram-scale preparation and some transformations
本研究报道了具有高区域选择性和立体选择性的钌( II )催化的内部炔烃的直接氢化硅烷化。这种标题转变导致各种乙烯基硅烷的产率从良好到极好。该方法具有反应条件温和、催化剂负载量低、空气稳定性好、官能团耐受性好等特点。此外,对乙烯基硅烷进行了克级制备和一些转化,进一步强调了其合成效用和适用性。
