Abstract:
A method for producing a cyclic carbonate represented by the following formula (1):
wherein X1 and X2 are the same as or different from each other, and are each a hydrogen atom, a fluorine atom, or a monovalent organic group; and R is an organic group containing one or more carbon-carbon unsaturated bonds. The method includes reacting an unsaturated cyclic carbonate represented by the following formula (A):
wherein X1 and X2 are defined as described above, and an alcohol represented by the formula (B): R—OH, wherein R is defined as described above, or an alkoxide thereof in the presence of a base, or reacting the unsaturated cyclic carbonate and the alkoxide. Also disclosed is a method for producing a cyclic carbonate.
