摘要：

(Chemical Equation Presented) Sidestepping a cyclic side product: Copolymerization of terminal epoxides with CO2 was investigated by using a cobalt(III) complex bearing a piperidinium end-capping arm and a piperidinyl arm (see scheme; DME = 1,2-dimethoxyethane). The catalyst system can selectively produce copolymers without contaminant formation of cyclic carbonates even at high conversion of the epoxide (> 99 %). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
