omega-dichloroperfluoroalkanes, the similarly stepwise reactions with an alkene is not clean, both bis-adducts and the corresponding omega-hydrides, RCH(2)CH(2)(CF(2))(n)()H as byproducts are also formed. In the absence of alkenes or alkynes, per- and polyfluoroalkyl chlorides can be converted to their sulfinate salts and sulfonyl chlorides.

Provided is a method for producing a cyclic carbonate obtained by reacting epoxide and carbon dioxide, the method being capable of efficiently producing a cyclic carbonate at a high conversion rate and a high yield, in which degradation of the catalyst over time is suppressed and catalytic activity hardly decreases.
A method for producing a cyclic carbonate by reacting epoxide and carbon dioxide in the presence of a quaternary onium salt selected from the group consisting of a quaternary ammonium salt having a halogenated anion as a counter ion and a quaternary phosphonium salt having a halogenated anion as a counter ion, or in the presence of a solid catalyst obtained by immobilizing the quaternary onium salt onto a carrier, wherein an organohalogen compound containing at least one halogen atom in one molecule is added to the reaction system.
