The synthesis of a fluorinated tridentate imidazolium salt (I) is used to generate both transition metal complexes (Ni, Pt, Pd) and hypervalent compounds from main group elements (P, Sb).1,2 Treatment of this salt with a base results in the formation of a stable zwitterion (II). Subsequent oxidation of the zwitterion produces the "spiroketal" structure (III). A unique feature of this "spiroketal" is the accessibility as a tridentate carbene ligand in transition metal complexes (IV) by reduction with a metal. The chemistry and reactivity of (III) will be reported along with the ability of the tridentate ligand to form transition metal complexes and hypervalent compounds (V).
