Tris(pentafluoroethyl)difluorophosphorane: A Versatile Fluoride Acceptor for Transition Metal Chemistry.

ABSTRACT: Fluoride abstraction from different types of transition metal fluoride complexes [L_n MF] (M=Ti, Ni, Cu) by the Lewis acid tris(pentafluoroethyl)difluorophosphorane (C₂ F₅ )₃ PF₂ to yield cationic transition metal complexes with the tris(pentafluoroethyl)trifluorophosphate counterion (FAP anion, [(C₂ F₅ )₃ PF₃ ]^- ) is reported. (C₂ F₅ )₃ PF₂ reacted with trans-[Ni(iPr₂ Im)₂ (Ar^F )F] (iPr₂ Im=1,3-diisopropylimidazolin-2-ylidene; Ar^F =C₆ F₅ , 1 a; 4-CF₃ -C₆ F₄ , 1 b; 4-C₆ F₅ -C₆ F₄ , 1 c) t
