Ethyl 3,3,3-trifluoropropanoate and ethyl 2-bromo-3,3,3-trifluoropropanoate have been synthesized. A common intermediate ethyl 3-chloro (or 3-bromo)-3,3-difluoropropanoate is involved in the two syntheses. These esters are obtained by oxidation of the corresponding acetals resulting from the radical addition of CF2BrCl or CF2Br2 to ethyl vinyl ether.
