Significant efforts have been devoted to develop an efficient catalytic system without the use of cocatalysts for conversion CO2 cyclocarbonate. However, low adsorption on surfaces catalysts is generally attributed their specific surface area and thermodynamic stability. Herein, we report efficacy a composite heterogeneous catalyst prepared by coating In2O3 with aniline-based polymers subsequent coordination hydrogen-bond donating functional groups (HBD). This shows high performance epoxide ring-opening reactions (99%) excellent recycling (sixth run) under mild conditions need cocatalysts. In contrast, polymer significantly reduced. study presents feasible strategy building HBD sites into CO2-adsorptive polymer-coated realizing cycloaddition reaction in aerobic environment.

One use of CO2 as a starting material in organic transformations is the synthesis cyclic carbonates and polycarbonates. Due to low reactivity CO2, this transformation must be carried out presence an efficient catalyst. Although several catalytic systems have been developed past decade, reducing pressure at which reaction remains one main challenges process. In context, present work, we describe activity mixed metal oxides from (1 atm) epoxides 70 °C. Using these materials catalysts represents significant benefits since they are very stable, cost-effective, can reused cycles.
