(Image Presented) The 100% atom-economical reaction between epoxides and carbon dioxide to give either cyclic carbonates or polymers is extremely attractive as part of the process of establishing more sustainable material and chemical industries in the future. Cyclic carbonates are already recognised as non-toxic polar aprotic solvents and chemical intermediates and are widely used as electrolytes for lithium-ion batteries. Polycarbonates prepared via this route have a great deal of potential, both as replacements for conventional polycarbonates and as polyols for the production of polyurethanes. Here, we highlight some of the more sustainable catalytic systems for each reaction, focusing on those with good activity which do not require the use of halides.
