Ni-catalyzed Reductive Carboxylation of Cyclopropyl Motifs with CO2

Abstract

A nickel-catalyzed reductive carboxylation technique for the synthesis of cyclopropanecarboxylic acids has been developed. This user-friendly and mild transformation operates at atmospheric pressure of carbon dioxide and utilizes either organic halides or alkene precursors, thus representing the first example of catalytic reductive carboxylation of secondary counterparts lacking adjacent π-components.
