Visible-light promoted arene C–H/C–X lactonization via carboxylic radical aromatic substitution

Author affiliations

Abstract

We report herein a photocatalytic arene lactonization via carboxylic radical aromatic substitution. This procedure is characterized by its ability to cleave inert C–X bonds (X = H, F, Cl, Br, O, S) under mild and oxidant-free conditions, thus furnishing a general and operationally simple synthetic protocol for diverse substituted coumarins.
