Abstract: Unprecedented enantioselectivity and catalytic activity was observed in the asymmetric copolymerization of CO2 with meso-epoxides (including the less reactive cyclopentene oxide) mediated by the dinuclear Co(III) complex (S,S,S,S)-1 under mild conditions. The resultant copolymers possess more than 99 % carbonate linkages and a perfectly isotactic structure.Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
