-1- Abstract of disclosure: : perfluoroisopropylketocarboxylic acid fluorides I Image in which N = a number from 0 to 9, are prepared by electrolysis of the w-hydro-perfluoro-(2-methyl-alkan-3- ones) VI Image in which m = a number from 1 to 10, in fluorosulfonic acid/alkali metal fluorosulfonate and decomposition of the w-fluorosulfato-(2-methyl-alkan-3-ones) V thereby formed Image in which m has the above meaning, in the presence of catalytic amounts of an alkali metal fluoride and in the absence of polar aprotic solvents. The w- fluoro- (sulfato-(2-methyl-alkan-3-ones v are new compounds. The perfluoroisopropylketocarbozylic acid fluor- ides I are intermediates for the preparation of per- fluorinated ketocarboxylic acid esters which have an iso- propyl radical adjacent to the keto group and are in -2- turn, in particular, valuable heat transfer fluids and surfacc-active agents with a high stability to chemicals and heat.
