Cobalt(II)-exchanged X and Y zeolites with varying metal loadings were employed to convert CO2 cyclic carbonates starting from alkenes. The transformation was carried out using O2 as an oxidant in a mixture of under atmospheric pressure, maximum yield 35.7% carbonate achieved. Studies revealed stark difference among both the zeolites, primarily arising their ion exchange behaviors. Their catalytic recyclability properties differed result this variation.

In this work, chromium(III) Salophen complexes bearing tertiary dimethyl or diethyl amino substituents were synthesized and tested as homogeneous co-catalysts associated with n-Bu4NBr for the cycloaddition of CO2 on styrene epoxide under 11 bar CO2. Full conversion oxide into carbonate was obtained after 23 h reaction at 50 °C using Salophen-Me2N-Cr. These results emphasized that amine groups born by aromatic cycles clearly enhanced co-catalytic activity corresponding Cr(III) complex.
