Bio-based cyclic carbonates
WebFunctionalized cyclic carbonates are attractive monomers for the synthesis of innovative polycarbonates or polyurethanes for various applications. Even though their synthesis has been intensively investigated, doing so in a sustainable and efficient manner remains a challenge. Herein, we propose an organocatalytic procedure based on the … WebParticularly, more green and renewable catalyst systems have attracted increasing attention. For instance, new catalytic systems based on biopolymers, such as cellulose [15], wool [4], chitosan [18], β-cyclodextrin [29] and lignin [27], have been studied for the synthesis of cyclic carbonates from CO 2 and epoxides. In particular, lignin-based ...
