Recent Advances in the Chemical Fixation of Carbon Dioxide: A Green Route to Carbonylated Heterocycle Synthesis

Abstract

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.

Conversion of CO2 into Chloropropene Carbonate Catalyzed by Iron (II) Phthalocyanine Hypercrosslinked Porous Organic Polymer

“…Thus, a great variety of homogeneous and heterogeneous catalysts have been explored to carried out this reaction to selectively obtain cyclic carbonates [ 2 , 3 ], which are extensively used as solvents to remove oils, as intermediates in organic synthesis or as monomers of plastics’ engineering [ 4 ].…”

Bypassing the Inertness of Aziridine/CO2 Systems to Access 5‐Aryl‐2‐Oxazolidinones: Catalyst‐Free Synthesis Under Ambient Conditions

“…In particular, oxazolidinones are five‐membered heterocyclic compounds that find important applications for their biological activity and as synthetic precursors to various natural and bioactive compounds . The recent years have witnessed an intense investigation aimed to develop new straightforward synthetic processes to access such fine chemicals exploiting CO 2 fixation routes . All of the reported methods require the use of a catalyst unless high CO 2 pressure or supercritical carbon dioxide is employed .…”

Oxidative carboxylation of olefins with CO2: environmentally benign access to five-membered cyclic carbonates

“…The use of carbon dioxide (CO 2 ) as a building block for the synthesis of high-value ne chemicals is receiving growing interest in the context of sustainable and green chemistry because it is a cheap, plentiful, non-toxic, non-ammable and renewable compound. [1][2][3][4][5][6][7][8][9][10] However, due to its high thermodynamic stability and chemical inertness, the efficient xation of this greenhouse gas into chemical products is a challenging issue as decarboxylation reactions can readily occur. 11 A strategy to overcome the low reactivity of CO 2 is based on the reactions with high free energy substrates.…”
