  The present invention provides a method for fixing carbon dioxide gas as a carbonyl compound represented by formula (3) as depicted by Figure 1 and comprising, purging of carbon dioxide in a solution of a nucleophile represented by the formula (1) in presence of a solvent at a temperature ranging from -40 Degree Celsius to 35 Degree Celsius, followed by adding a reagent at temperature ranging from -40 degree to 35 degree and thereafter adding another nucleophile represented by the formula (2) to obtain carbonyl compound represented by formula (3). The present invention can be advantageously used to obtain commercially important carbonyl compounds and clean unwanted carbon dioxide gas from the atmosphere and industrial effluents.

  The synthesis of N,N′-dialkylurea from carbonylation of amines with CO2 over δ-MnO2 catalyst is a highly attractive green route, however, the catalytic performance of δ-MnO2 is still far from satisfied. Here, we report a new strategy for fine tuning the physicochemical properties of δ-MnO2 through KOH hydrothermal activation, resulting in superior catalytic performance with N,N′-dialkylurea yield as

  胺与CO 2在δ-MnO 2催化剂上羰基化合成N,N'-二烷基脲是一条极具吸引力的绿色路线，但δ-MnO 2的催化性能仍远未满足。在这里，我们报告了一种通过 KOH 水热活化微调 δ-MnO 2的物理化学性质的新策略，在 160 °C 下使用 NMP 作为溶剂，N,N'-二烷基脲产率高达 77.09%，从而获得了优异的催化性能。 4 小时，而原始 δ-MnO 2仅为 43.41%. 通过使用 PEG 400 作为溶剂，产率进一步提高到 92.02%。基于表征技术的系统分析表明，这种优异的催化性能一方面与钾的掺入和催化引起的氧和锰空位浓度的改变密切相关，另一方面，作为溶剂的 PEG 400有利于CO 2的吸收和氨基甲酸中间体的稳定性。
