Synthesis of Cyclic Carbonates from Olefin Oxides and Carbon Dioxide. Communication 2. Catalysis by Metal Porphyrin Complexes.

The catalytic systems based on metal porphyrin complexes used for promoting the reactions of olefin oxides with carbon dioxide were reviewed. The metal porphyrin complexes were shown to be effective catalysts for carboxylation of epoxides. The catalyzed reactions of oxiranes with carbon dioxide in the presence of homogeneous and heterogeneous metal porphyrin complexes, including the reactions with the use of various promoting additives, were considered.
