A Green Chemo-Enzymatic Approach for CO₂ Capture and Transformation into Bis(cyclic carbonate) Esters in Solvent-Free Media.

ABSTRACT: A sustainable approach for CO₂ capture and chemo-enzymatic transformation into bis(cyclic carbonate) esters from CO₂, glycidol, and organic anhydrides under solvent-free conditions has been demonstrated. The chemo-enzymatic process is based on two consecutive catalytic steps, which can be executed through separated operations or within a one-pot combo system, taking advantage of the synergic effects that emerge from integrating ionic liquid (IL) technologies and biocatalysts. In a first step, lipase-catalyzed transesterification and esterification reactions of different diacyl donors (e.g., glutaric anhydride, succinic anhydride, dimethyl succinate, etc.) with glycidol in solvent-free under mild reaction conditions (70 °C, 6 h) produce the corresponding diglycidyl est
