Abstract

The Lewis acid-mediated direct carboxylation of aromatic compounds with C[O.sub.2] efficiently promoted by the addition of silyl chlorides bearing three alkyl and/or aryl substituents in total on the silicon atom is described. Based on the finding for the mass balance related to silicon which showed the silyl chlorides to be recycled during the reaction sequence, a feasible mechanism is proposed for the present carboxylation.
