Visible Light‐Promoted Aerobic Oxidation of α‐Silyl Styrenes with Alcohols

Abstract

Comprehensive SummaryA mechanistically distinctive visible‐light‐promoted metal‐free aerobic oxidation of alkenyl silanes with alcohols was disclosed to efficiently construct α‐alkoxy ketones under mild conditions. The primary, secondary, and tertiary alcohols could be used as reactants. The protocol could be carried out on a gram‐scale. Various derivatizations of products could be conducted. Mechanistic studies indicated the reaction was initiated by single‐electron oxidation of the alkenyl silanes, rather than radical addition to alkenyl silanes.
