Silylations remain a longstanding challenge in organic synthesis. While much recent work has focused on the use of first-row transition metals to perform silylations, catalysts based on platinum and palladium remain the catalysts of choice. One of the challenges of copper-catalyzed silylations is the use of specialized silicon reagents, such as silylboranes, that are required to create the intermediate
甲硅烷基化仍然是有机合成中的长期挑战。尽管许多最新工作集中在使用第一行过渡金属进行甲硅烷基化的过程中,但基于铂和钯的催化剂仍然是选择的催化剂。铜催化的甲硅烷基化的挑战之一是使用特殊的硅试剂,例如甲硅烷基硼烷,这是生成中间体铜甲硅烷基络合物所必需的。甲硅烷基硼烷在铜催化方面已取得相当大的成功,但它们对空气和水敏感,使其难以使用,并且难以合成或购买昂贵。本文中,我们报道了由易于处理且相对廉价的乙硅烷合成铜甲硅烷基络合物的方法。配合物的结构通过X射线晶体学确认,
