  Onium salt, N1, N1, N1, N5, N5, N5-hexaethylpentane-1,5-diammonium dibromide, was used as a catalyst for the addition of CO2 to epoxides. An influence of insoluble supports on the rate of the process as well as possibility of recycling of the catalytic system are described. In addition, the effects of temperature and CO2 pressure on the yields of products are discussed.

  complex study of sodium and potassium halides as catalysts of the addition of CO2 to epoxides to yield organic carbonates was carried out. The activity of these metal iodides was investigated. The conditions allowing achievement of a quantitative conversion of epoxides into carbonates were found by varying the temperature, carbon dioxide pressure, and available co-solvents.

  easy-to-prepare recyclable catalyst of quaternary ammonium nature and based on commercially available and inexpensive macroporous polymeric sorbent Purolite A103 resin has been devised for the carbon dioxide addition to epoxides. The catalyst can be easily separated due to its 0.6–0.85 mm bead size and recycled at least seven times. The catalyst makes it possible to carry out the reaction under solvent-free conditions
