| Abstract: |
| Recently, green chemistry has attracted substantial consideration difficult to overcome of CO2 as greenhouse gases encountered by the world population. To solve this problem, CO2 could be used as a safe, cheap, and renewable C1 building block to synthesize useful organic compounds such as dimethyl carbonate, formic acid, urethanes, cyclic carbonates, methanol, polycarbonates, and others have been prepared by using CO2 as a feedstock. One of these methods is through the carboxylative cyclization of propargylic amines with CO2 for synthesis 2-oxazolidinones that have important role as chemical intermediates, chiral auxiliaries, and antibacterial drugs. Ionic liquid is an essential and efficient catalyst for the making of industrial chemicals and thousands tons of IL is annually consumed as a catalys which need costly and difficult separation of the catalyst from homogeneous reaction mixtures. For solving this problem, the use of solid ionic liquid has reported important advantages in organic synthesis, such as operational simplicity, non-toxicity, environmental adaptability, low cost, reusability, and ease of isolation. The use of recyclable strong solid ionic liquids in organic reactions are often considered to follow the principles of green chemistry, that is these catalyzed processes consume a minimum of energy and reagents or auxiliaries and minimize waste. Magnetic ionic liquid is easier to handle than ionic liquid and can readily be separated from the products by an external magnet. Herein, we report the synthesis of a new class of ionic liquid heterogeneous magnetic catalyst in which magnetic nanoparticles were coated by KCC-1 functionalized IL and used in the chemoselective synthesis of cyclic carbonates. At the end of reaction the catalyst can be easily separated by an external magnet, without using extra organic solvents and additional filtration steps. Morphology and structure of the as-prepared materials were characterised by TEM, XRD and TGA |
