Abstract: A method of making a polyfunctional polyfluorinated compound includes combining first components that include a polyfluorinated cyclic compound having 4 to 7 ring carbon atoms and at least one of osmium tetroxide, ruthenium tetroxide or a precursor thereof and forming a polyfluorinated dicarboxylic acid. Two of the ring carbon atoms of the polyfluorinated cyclic compound form a double bond or an epoxide. The precursor reacts with an oxidant to form ruthenium tetroxide. Methods also include converting the polyfluorinated dicarboxylic acid to a polyfluorinated dicarboxylic acid halide and converting the polyfluorinated dicarboxylic acid halide to other polyfunctional polyfluorinated compounds.
