2-chloro-1,2,2-trifluoroethyl ketones and aryl 1,2,2,2-tetrafluoroethyl ketones were respectively prepared by the Friedel–Crafts acylation of trifluoroethene and by the Grignard arylation of N,N-diethyl-1,2,2,2-tetrafluoropropionamide, a hydrolyzed product of hexafluoropropene–diethylamine adduct. These alkyl and aryl polyfluoroalkyl ketones were subjected to base-induced dehydrohalogenation, and resulting
烷基2-氯-1,2,2-三氟乙基酮和芳基1,2,2,2-四氟乙基酮分别通过三氟乙烯的Friedel-Crafts酰化和N,N-diethyl-1的格利雅芳基化制备, 2,2,2-四氟丙酰胺,六氟丙烯-二乙胺加合物的水解产物。这些烷基和芳基多氟烷基酮经过碱诱导脱卤化氢,得到的三氟乙烯基酮原位水解,以良好的产率得到α-氟-β-酮酯。
