A process for the preparation of trifluoroacetyl fluoride is disclosed, which comprises reacting, in the liquid phase, hexafluorothioacetone dimer in an aprotic solvent with at least a catalytic amount of an alkali metal fluoride in the presence of an oxidizing agent selected from the group consisting of Ag2O, oxides of Pb, Sn, Ni, Co and Fe and M2S2O8 wherein M is an alkali metal. The preferred aprotic solvent is dimethylformamide; the preferred alkali metal fluoride is KF; and the preferred oxidizing agents are NiO, PbO2, and M2S2O8 wherein M is Na or K.
