Production of cyclic carbonate

The purpose of the present invention is to provide a practical method for producing a cyclic carbonate, which is widely used for various applications such as electrolytic solutions for lithium-ion secondary batteries and plastic materials, by a reaction between an epoxide (oxirane) and carbon dioxide, the method giving consideration to the reduction of environmental loads and making it possible to produce said cyclic carbonate with high yield under mild conditions, such as at room temperature and atmospheric pressure. The present invention relates to a method for producing a cyclic carbonate, the method being characterized by reacting an epoxide and carbon dioxide in the presence of an iodine-anion-containing phosphonium salt and a compound including a hydrogen atom that can form a hydrogen bond with an oxygen atom in the epoxide.

Effective synthesis of cyclic carbonates from carbon dioxide and epoxides by phosphonium iodides as catalysts in alcoholic solvents

Phosphonium iodides effectively catalyzed the reaction of CO2 and epoxides under mild conditions such as ordinary pressure and ambient temperature in 2-propanol, and the corresponding five-membered cyclic carbonates were obtained in high yields.

A structural and spectroscopic study of tris-aryl substituted R 3PI2 adducts

A series of Ar3PI2 adducts [Ar = (o-OCH 3C6H4), (m-OCH3C6H 4), (p-OCH3C6H4), (o-SCH 3C6H4), (p-SCH3C6H 4), (m-FC6H4), (p-FC6H4), (p-ClC6H4)] have been synthesized via the 1:1 reactions of Ar3P with di-iodine. The 31P{1H} NMR spectra of a series of Ar3PI2 adducts has been examined to resolve previous inconsistent reports. Ar3PI2 adducts do not ionize to [Ar3PI]I in CDCl3, and in many cases the molecular Ar3PI2 "spoke" adduct is stable in solution, with the degree of stability being highly dependent on the nature of the aryl group. The structures of the majority of these adducts have been established by X-ray diffraction studies. Whilst P-I and I-I bond lengths are primarily influenced by electronic effects, steric and crystal packing effects may also have an influence, as shown by the different polymorphs of (p-FC 6H4)3PI2, where a change in the conformation of the aryl groups in one of the molecules results in a lengthening of the P-I bond and shortening of the I-I bond.
