Electroreduction of [CpFe(CO) 2 ] 2 (Fp 2 ) in the presence of carbon dioxide makes possible the formation of the 1:1 adduct [Cp(CO) 2 FeCO 2 ] − , which is catalytically reduced at −1.8 V vs SCE liberating [Cp(CO) 2 Fe] − and CO 2 ·− . The generation of CO 2 ·− at a potential close to the standard value allows regioselective carboxylation of styrene and isoprene with turnover number of 200 per Fp 2 . The first step of the carboxylation appears to be the addition of CO 2 ·− to the unsubstituted carbon atoms of the olefin. Copyright © 2000 John Wiley & Sons, Ltd.
