“…The production of cyclic carbonates from CO2 is fully atom-economical and uses a safe gas, instead of toxic gases such as phosgene. The reaction of carbon dioxide with epoxides [41][42][43][44][45] as well as with propargyl alcohols [2] has been widely reviewed in the past years. However, in the last two years a large production of research articles on this topic has appeared in the literature and they are summarized in Table 1.…”

Carbon dioxide produced by human activities is one of the main contributions responsible for the greenhouse effect, which is modifying the Earth’s climate. Therefore, post-combustion CO2 capture and its conversion into high value-added chemicals are integral parts of today’s green industry. On the other hand, carbon dioxide is a ubiquitous, cheap, abundant, non-toxic, non-flammable and renewable C1 source. Among CO2 usages, this review aims to summarize and discuss the advances in the reaction of CO2, in the synthesis of cyclic carbonates, carbamates, and ureas appeared in the literature since 2017.

The synthesis of solid catalysts for the co-catalyst-free cycloaddition of CO has attracted much attention. Herein, we report a hierarchical porous organic polymer, Py-Zn@MA, that is able to catalyze the cycloaddition reaction of epoxides and CO without using any additives or co-catalyst to afford turnover frequency (TOF) values as high as 250 and 97 h at 130 °C by using pure and diluted CO (simulating flue gas), respectively. These results are superior to those obtained from previously reported heterogeneous co-catalyst-free systems. The high activity of Py-Zn@MA is mainly attributed to its bifunctional nature with ZnBr and pyridine activating the epoxide in a cooperative way. Notably, Py-Zn@MA can be easily prepared on a large scale without using any catalyst and the chemicals are cost effective. Moreover, Py-Zn@MA shows good substrate universality for the cycloaddition reactions of epoxides. Our designed porous organic polymer Py-Zn@MA material has the potential to serve as an efficient catalyst for the direct conversion of flue gas with epoxides into value-added cyclic carbonates.

“…[1][2][3][4][5][6][7][8] In addition to being regarded as ag reenhouse gas, CO 2 is also an important carbon source. [9][10][11][12] In combination with sustainable H 2 or electricity, CO 2 can be converted to fuels or chemicals, which will help to maintain the carbon balance of Earth. [13][14][15] CO 2 capture is one of the key steps to achieving this goal.…”

CO capture is very important to reduce the CO concentration in atmosphere. Herein, we report the preparation of microporous polymers with tunable surface polarity for CO capture. Porous polymers functionalized with -NH , -SO H, and -SO Li have been successfully prepared by using a post-synthesis modification of microporous polymers (P-PhPh prepared with 1,3,5-triphenylbenzene as the monomer and AlCl as the catalyst) by chemical transformations, such as nitration-reduction, sulfonation, and cationic exchange. The CO adsorption selectivity (CO /N and CO /H ) and isosteric heats of the microporous polymers increase markedly after modification, P-PhPh -NH and P-PhPh -SO Li afford higher CO uptake capacity than P-PhPh at pressures of less than 0.15 bar due to the enhanced interaction between CO and the -NH and -SO Li functional groups. Moreover, functionalized porous polymers could be stably used for CO capture. Surface modification is an efficient approach to tune the CO capture properties of porous polymers.
