Electrophilic Aromatic Substitution of Arenes with CO2 Mediated by R3SiB(C6F5)4

Abstract

Abstract The Friedel–Crafts-type carboxylation of arenes has been achieved by activating CO2 with silylium borates. The reaction exhibits broader substrate applicability than does our previously reported AlX3/R3SiX-mediated carboxylation.
