Abstract

Electrophilic Aromatic Substitution of Arenes with CO 2 Mediated by R3SiB(C6F5)4. -The Friedel-Crafts-type carboxylation of arenes is achieved by activation of carbon dioxide with silylium borates. The reaction also proceeds under basic conditions which opens the applicability of the presented carboxylation to acid-sensitive compounds. -(KONNO, M.; CHIBA, M.; NEMOTO, K.; HATTORI*, T.; Chem.
