An effective direct method for preparing of cyclic carbonates from CO 2 and olefins in the presence of tert -butyl hydroperoxide as an oxidant was provided. The first stage, the epoxidation of olefins, was carried out using MoO 2 (acac) 2 as a catalyst (1h, 100 °C), and the second stage, the cycloaddition of CO 2 to the resulting epoxide, was proceeded in the presence of immobilized tributylmethylammonium chloride on a polystyrene cross-linked with divinylbenzene, and an aqueous solution of ZnBr 2 (100 °C, 0.9 MPa of CO 2 , 4 h). The proposed method allowed to obtain cyclic carbonates with high yields (50–77%) under mild conditions. Moreover, the immobilized catalyst could be reused at least five times without significant loss of its catalytic activity. Graphical Abstract
