Crosslinking investigations of perfluorinated systems employing metalloid compound initiated thermal cure and a functional epoxide approach are reported. Using triphenylphosphine and tetraphenyldiphosphine at temperatures up to 300 C, no reaction was observed with perfluoroalkylethers with perfluoromethylcyclohexane some fluorine abstraction took place but no coupling products could be identified. The presence of aromatic substituents resulted in perfluoroalkylether chain activation. A functional epoxide precursor, 4-bromoheptafluorobutene-1 was prepared and the Procedure for its oxidation to the epoxide was optimized.
