ABSTRACT:
A process for producing a fluorine-containing acrylic acid ester represented by CH2═C(Rf)(COOR) characterized in that 1-bromo-1-perfluoroalkylethene represented by CH2═CBr—Rf, or 1,2-dibromo-1-perfluoroalkylethane represented by CH2CBr—CHBr—Rf is allowed to react with an alcohol represented by ROH in the presence of a palladium catalyst, carbon monoxide, and two or more kinds of bases. The fluorine-containing acrylic acid ester is a useful compound having wide applications in materials for pharmaceuticals and functional polymers.
