PROCESS FOR PREPARING FLUORINATED COMPOUND

摘要

The present invention is directed to a fluorinated compound of the formula: R-CCl2CF2CF3 (I) in which R is a perfluoroalkyl group, a perchloroalkyl group, a polyfluoroalkyl group, a polychloroalkyl group or a polychloropolyfluoroalkyl group, each having at least one carbon atom. The fluorinated compound of the formula (I) is prepared with high selectivity and a high yield by reacting tetrafluoroethylene with a compound of the formula: R-CFCl2 (II) in which R is the same as defined above in the presence of a Lewis acid.
