Abstract

A nickel-catalyzed reductive carboxylation of styrenes using CO₂ proceeds under mild conditions using diethylzinc as the reductant. The catalyst system is very robust and will fixate CO₂ in good yield even if exposed to only an equimolar amount introduced into the headspace above the reaction.
