Divergent functionalization of aldehydes photocatalyzed by neutral eosin Y with sulfone reagents

Abstract

Acyl radicals represent a reactive species that allow for aldehyde subunits to be nucleophilic instead of their typical electrophilic behavior; however, these species are difficult to access in mild conditions. Here the authors show a method to generate acyl radicals using only an organic photocatalyst and light, and these species are shown as competent nucleophiles in a variety of couplings.
