A process for the carboxylation of an aryl halide to yield an aryl carboxylic acid, in which the aryl halide and CO2 are contacted in an organic solvent under inert atmosphere and in the presence of a reducing agent and an adequate catalyst system.

novel protocol for the direct carbon dioxide insertion (CO(2)) into aryl halides in a catalytic manner is presented herein. Unlike other carboxylation methods using CO(2), there is no need for the synthesis of the corresponding organometallic intermediates. Additionally, and in contrast to the well-established carbonylation processes, our protocol does not use highly toxic CO for the preparation of
