Nickel-catalyzed electrocarboxylation of allylic halides with CO2

Abstract

Nickel-catalyzed regioselective electrocarboxylation of allylic halides with CO₂ at atmospheric pressure has been developed by adjusting reaction parameters, including catalyst, solvent, temperature and additive. β,γ-Unsaturated carboxylic acids were obtained in moderate to good yields and with high chain selectivity. This reaction shows tolerance to functional groups. In addition, cyclic voltammetry was performed to provide the possible mechanism of nickel-catalyzed CO₂ allylation.
