Abstract

The increasing concentration of carbon dioxide (CO 2 ) in the atmosphere is partly responsible for the climate changes, while CO 2 is also regarded as a cheap, green C1 resource. 1 CO 2 is an environmentally friendly chemical reagent and is especially useful as a phosgene substitute. 2 One of the most important processes is incorporation of CO 2 into epoxides to give five-membered cyclic carbonates, 3 which are widely used as starting compounds for ...
