A method of producing a fluoroolefin includes contacting a compound of formula (1), RfCH=CHF, with a fluorinated ethylene compound of formula (2), CX1X2=CX3X4 in the presence of a Lewis acid catalyst. In the compound of formula (1), Rf is a C1-C10 perfluorinated alkyl group. In the compound of formula (2), X1, X2, X3, and X4 are each independently H, Cl, or F and at least one of X1, X2, X3, and X4 is F. The resulting composition comprises a compound of formula (3), RfCF3(CX5X6CX7X8)nCH=CHCX9X10CX11X12F. In the compound of formula (3), X5, X6, X7, X8, X9, X10, X11, and X12 are each independently H, Cl, or F, n is an integer of 0 or 1, and the total number of each of H, Cl, and F corresponds to the total number of each of H, Cl, and F provided by the fluorinated ethylene compound of formula (2).
一种制备氟代烯烃的方法,包括在路易斯酸催化剂的存在下,将式(1)化合物RfCH=CHF与式(2)氟代乙烯化合物CX1X2=CX3X4接触。在式(1)的化合物中,Rf是C1-C10全氟烷基。在式(2)的化合物中,X1、X2、X3和X4各自独立地是H、Cl或F,且至少一个X1、X2、X3和X4为F。所得到的组合物包括式(3)化合物RfCF3(CX5X6CX7X8)nCH=CHCX9X10CX11X12F。在式(3)化合物中,X5、X6、X7、X8、X9、X10、X11和X12各自独立地是H、Cl或F,n是0或1的整数,H、Cl和F的总数对应于式(2)氟代乙烯化合物提供的H、Cl和F的总数。
