Water as an Efficient Medium for the Synthesis of Cyclic Carbonate
Tetrahedron Letters, 2009 Herein, we report a novel method for the synthesis of cyclic carbonate in water. By tuning the amount of water, cycloaddition Of CO(2) to epoxide in aqueous medium leads to cyclic carbonates with moderate to excellent yields and high selectivities.

Safer Polyurethane Foams with Cyclic Carbonates
Angewandte Chemie, 2023AbstractPolyurethanes (PUs) are a class of materials usually synthesized from isocyanates, diols, and water. Water is essential for producing carbon dioxide (CO2) which is used for the self‐blowing of the foams. Due to safety concerns with the production of isocyanates, alternative chemistries have been evaluated and cyclic carbonate systems have shown

Abstract Hydroiodides of amidines can catalyze the reaction of carbon dioxide and epoxides under mild conditions such as ordinary pressure and ambient temperature, and the corresponding five-membered cyclic carbonates were obtained in high yields. The reaction of epoxide with carbon disulfide was also examined under the same conditions.

Synthesis of cyclic carbonates with carbon dioxide and cesium carbonate
Green Chemistry, 2013Cyclic carbonates are important compounds for the synthesis of biocompatible polymers and linear dialkyl carbonates, as well as solvents and electrolytes. We report here the synthesis of such compounds from easily accessible starting materials with carbon dioxide as a C1 source and caesium carbonate as the base. This new methodology is able to yield 5-

Cyclic Carbon Cluster Dianions and Their Aromaticity
Journal of the American Chemical Society, 2002Cyclic carbon cluster dianions (CC(2))(2-)(n)(n = 3-6) are investigated by ab initio methods with regard to their geometric properties, electronic stability, and aromaticity. The unique wheel-like structures of these dianions consist of a n-membered carbon ring, where a C(2) unit is attached to each carbon atom.

Planar Tetracoordinate Carbons in Cyclic Hydrocarbons
Organic Letters, 2005[structure: see text] A series of cyclic hydrocarbons containing a planar tetracoordinate carbon atom is proposed. To rationalize the electronic factors contributing to the stability of these molecules, an analysis of the molecular orbitals and the induced magnetic field is presented.
