Fluorinations with potassium tetrafluorocobaltate(III). Part II. Fluorination of ketones

Abstract

Diethyl ketone, hexafluoroacetone, and hexachloroacetone have been fluorinated over potassium tetrafluoro-cobaltate(III) to give polyfluoroacyl fluorides as the major products. Diethyl ketone was completely cleaved by cobalt(III) fluoride, though heptafluoro-n-propyl methyl ketone gave heptafluorobutyryl fluoride.
