“…Prior to this study, Rybina and coworkers have reported that in the presence of dimethylformamide, CoCl 2 Á 6H 2 O could catalyze the cycloaddition of CO 2 to epoxides at elevated temperatures. 28 Interestingly, Darensbourg and Moncada found that the salenCo(II) complex 3 in the presence of an anionic-based cocatalyst derived from n Bu 4 NX (X = Cl, N 3 , Br, I) salts to be very effective in catalyzing the coupling of oxetane and CO 2 to provide the corresponding polycarbonate with minimal amount of ether linkages. 29 The mechanistic study by means of in situ infrared spectroscopy revealed that an intermediate, six-membered cyclic carbonate (trimethylene carbonate) was first formed via a backbiting mechanism.…”

“…This happens also to the 2,2-difluoro-4-propyl-1,3-dioxolane ( 12h ) prepared from 11h and BrF 3 . If not kept strictly anhydrous, 12h quickly hydrolyzed to O , O -(1,2-pentane)carbonate ( 13h ) (Scheme ). Similar behavior was noted when 2,2-difluoro-4-(methoxymethyl)-1,3-dioxolane ( 12i ) was converted to 4-propyl-1,3-dioxolan-2-one ( 13i ) in 75% yield.…”

As an abundant, nontoxic, nonflammable, easily available, and renewable carbon resource, development of catalytic processes for chemical transformation of CO 2 into useful chemicals/materials/fuel is of paramount importance from the standpoint of green and sustainable chemistry. Great progress has been made in catalytic utilization of CO 2 as an alternative to phosgene and/or carbon monoxide in organic synthesis, mainly adopting high‐energy starting materials to produce low‐energy synthetic targets including cyclic carbonates, dialkyl carbonates, and polycarbonates (C‐O bond formation); oxazolidinones, quinazolines, urea derivatives, carbamates, isocyanates, and polyurethanes (C‐N bond formation); carboxylic acids and its derivatives (constructing C‐C bond); and formic acid derivatives, methanol and methane (C‐H bond formation via hydrogenation). However, the CO 2 molecule poses inherent thermodynamic stability and kinetic inertness because it is the most oxidized state of carbon. In this context, specific methodologies associated with the design of robust catalysts and choice of proper reaction media, such as specially designed transition‐metal containing complexes/ligands, using functionalized ionic liquids (ILs) and organocatalysts like frustrated Lewis pairs (FLPs) and using supercritical CO 2 (scCO 2 ), have been developed on the basis of underlying principles of activation of CO 2 while gaining insight into its mechanism at the molecular level. The challenge is to develop easily prepared, efficient, and recyclable catalysts that are capable of activating CO 2 under low pressure (preferably at 1 atm) and, thus, incorporating CO 2 into organic molecules catalytically.
