Metal‐Free Organophotocatalyzed Trifluoroethylation/Esterification of Alkenes

Abstract A metal‐free, organophotocatalyzed three‐component reaction between alkenes, 2,2,2‐trifluoroiodoethane, and carboxylic acids was developed. This protocol simultaneously introduces a trifluoroethyl group and an ester moiety in a single step. Preliminary mechanistic studies suggest the reaction proceeds via a radical pathway.
