Abstract

An energetically and atom economic transfer hydrosilylation of ketones employing silyl formates as hydrosilanes 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% yield in the presence of a PNHP-based ruthenium catalyst and silyl formate reagent. The crucial role of the ligand for the transformation is demonstrated.
