Unprecedentedenantioselectivity and catalytic activity was observed in the asymmetriccopolymerization of CO2 with meso‐epoxides (including the less reactive cyclopentene oxide) mediated by the dinuclear CoIII complex (S,S,S,S)‐1 under mild conditions. The resultant copolymers possess more than 99 % carbonate linkages and a perfectly isotactic structure.
