Abstract
A transfer hydrosilylation of ketones employing silyl formates as hydrosilane surrogates under mild conditions is presented. A total of 24 examples of ketones have been successfully converted to their corresponding silyl ethers with 61-99% yields in the presence of a PNP-based ruthenium catalyst and silyl formate reagent. The crucial role of the ligand for the transformation is demonstrated.
摘要
本文提出了一种在温和条件下，利用硅基甲酸酯作为硅烷替代物进行酮的转移氢化硅烷化反应的方法。在 PNP 基钌催化剂和硅基甲酸酯试剂的存在下，24 个酮的实例被成功地转化为相应的硅醚，产率为 61-99%。实验结果证明了配体在转化过程中的关键作用。
