Abstract: Carbon dioxide, a greenhouse gas that negatively affects the climate of our planet, which makes the problem of CO2 utilization more and more acute.One of the options for the utilization of CO2 is the possibility of using it as a carbon source for the synthesis of chemicals.Organic carbonates have a wide range of applications, in particular, they are used in pharmacological and agricultural chemistry to obtain medicines and agricultural products, in polymer chemistry to obtain new monomers and polymers based on them, as well as syntono (intermediate intermediates), reagents and highly selective solvents..The existing technologies for the synthesis of organic carbonates involve the use of phosgene, a rather toxic and expensive substance, which leads to serious environmental problems.Therefore, the development of new, environmentally friendly processes, especially with the use of various epoxides and CO2, is an extremely topical issue.The main goal of this work is the development of fundamentally new, cheap and "green" catalytic systems for receiving of organic carbonates with cyclic structure.For this purpose, the process of obtaining ethylene carbonate is based on the reaction of cycloaddition of CO2 and ethylene oxide in the presence of various new zinc phenolate (methylene-bis-, thio-bisand dithio-bis zinc phenolates) catalysts
