Electroreductive carboxylation of benzylphosphonium salts with CO2 through the cleavage of the C(sp3)–P bond

Abstract

Herein, a electroreductive carboxylation of benzylphosphonium salts was achieved by the cleavage of the C(sp³)–P bond, and various valuable arylacetic acids could be synthesized by this strategy. Also, based on control experiments and previous studies, a plausible reaction mechanism was proposed to explain the reaction process. The establishment of this procedure will provide a new paradigm for the functionalization of alkyl phosphonium salts.
