Chemistry of the metal carbonyls. Part XLII. Reactions between carbonylmetal anions and perfluoropyridine, perfluoropyridazine, or cyanuric fluoride

Abstract

Treatment of perfluoropyridine, perfluoropyridazine, or cyanuric fluoride with certain carbonylmetal anions affords organometallic complexes wherein NC₅F₄, N₂C₄F₃, and N₃C₃F₂ heterocyclic rings are σ-bonded to transition metals. The three nitrogen heterocycles are more reactive than hexafluorobenzene towards carbonylmetal anions so that the relatively week nucleophiles [Mn(CO)₅]^– and [π-C₅H₅Mo(CO)₃]^– give complexes. The ¹⁹F n.m.r. spectra of the compounds are described, as are certain other properties.
