Carbonylation of Alkyl Radicals Derived from Organosilicates through Visible-Light Photoredox Catalysis

Abstract

Primary, secondary, and tertiary alkyl radicals formed by the photocatalyzed oxidation of organosilicates underwent efficient carbonylation with carbon monoxide (CO) to give a variety of unsymmetrical ketones. This study introduces the possibility of radical carbonylation under a photooxidative regime.

Keywords: carbonylation; photocatalysis; radicals; silicates; three-component reactions.
