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.
合成了3,3,3-三氟丙酸乙酯和2-溴-3,3,3-三氟丙酸乙酯。常见的3-氯(或3-溴)-3,3-二氟丙酸乙酯中间体参与了这两种合成。这些酯通过将CF 2 BrCl或CF 2 Br 2自由基加成到乙基乙烯基醚中而得到的相应缩醛氧化而获得。
