The synthesis of cyclic carbonates from epoxides and carbon dioxide using sustainable metal-based catalysts is critically reviewed.
The use of sustainable metal-based catalysts for the synthesis of five-membered ring containing cyclic carbonates from epoxides and carbon dioxide is critically reviewed. Coverage is restricted to catalysis by the abundant metals: sodium, potassium, aluminium, calcium, titanium and iron and the relative merits and limitations of each catalyst system are compared.
