Article Title: Toward the design of double metal cyanides for the copolymerization of CO(2) and epoxides.
Article Snippet: The coupling of CO2 and epoxides to afford polycarbonates has received increased interest over the past decade,1 following the initial discovery of this process by Inoue in 1969.2 Indeed, research activity in this area is spurred on by the potential of synthesizing these extremely important thermoplastics via an environmentally benign route.3 Further progress in this endeavor is hindered by the observation that upon replacing alicyclic epoxides, such as cyclohexene oxide, with aliphatic epoxides, cyclic carbonate production is dominant over polycarbonate formation at desirable reaction conditions.4 In the patent literature there exists a heterogeneous catalyst system which appears to overcome some of the shortcomings of the recently developed homogeneous catalysts which are so active for alicyclic epoxides.5 This catalyst system is referred to as a Double Metal Cyanide (DMC) and is comprised of a metal ion (M1) which form a strong bond to oxygen and a metal (M2) cyanide salt, e.g., [M]n[M(CN)6]m. One of the most preferable catalyst precursors is zinc hexacyanoferrate(III).. To achieve high activity with these catalysts, an organic coordinating reagent is also required, such as an alcohol.. Similar catalysts are also shown to be useful for epoxide polymerization to polyethers.6 Nevertheless, these rather complex catalysts are poorly defined with respect to a detailed understanding of their structures and reaction pathways.
