-hexaethylpentane-1,5-diammonium dibromide, was used as a catalyst for the addition of CO
2
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 CO
2
pressure on the yields of products are discussed.
