Abstract

Fluorinated carbonyl compounds are prepared by contacting a fluorinated methyl ether containing at least one methoxylated carbon atom- containing group selected from -CF2OCH3, =CFOCH3, <IMAGE> and <IMAGE> with a catalyst selected from SBX5, TaX5, NbX5, AsX5, BiX5TiX4, ZrX4, HfX4, AlX'G3, FeX3, mixtures of SbX3 and SbX5, ZM'X''6, and mixtures of ZM'X''6and M'X5 where X, independently, is F, Cl, Br or I, X', independently, is Cl, Br or I, and X'' is F or Cl, Z is H, NO, O2, alkali metal or NY4 where Y, independently, is H or alkyl of 1 to 6 carbon atoms, and M' is Sb or As at a temperature of -20 DEG to 200 DEG C.
