4065 4065 1 10/11/21 20211007 NES 211007 B The Cover Feature b highlights the successful use of gallium aminotrisphenolate compounds as catalysts for the synthesis of cyclic carbonates from CO SB 2 sb and epoxides. In their Full Paper, L. Álvarez-Miguel et al. highlight the facile synthesis of the gallium compounds, demonstrate their wide substrate scope when employed as catalysts for cyclic carbonate synthesis and compare the gallium compounds to their aluminium congeners, through both experiments and a detailed DFT study.

The Cover shows a state‐of‐the‐art aluminum porphyrin‐based hyper‐crosslinked polymer for the chemical fixation of CO2 into cyclic carbonates under mild conditions.In their Full Paper, Y. J. Chen et al. demonstrate the outstanding catalytic activity and excellent reusability of aluminum porphyrin‐based heterogeneous catalysts in the solvent‐free synthesis of cyclic carbonates from epoxides and CO2 in the presence of tetrabutylammonium bromide as cocatalyst.
