Carbon dioxide is a main greenhouse gas. It is also a cheap, nontoxic, andabundant carbon source. Hence, development of green, efficient and inexpensive wayto fix carbon dioxide into useful chemical products has attracted widespread attentionin recent years. It was recently reported that, one of the most effective method ofchemical fixation of CO_2is the coupling reaction of epoxide and CO_2to generatecyclic carbonates. Considering the problems in cycloaddition of CO_2and epoxide toproduce cyclic carbonate,...
