Syntheses and Properties of Pentafluoroethylplumbanes in the Oxidation States +II, +III, and +IV

ABSTRACT Mono‐, bis‐, and tris(pentafluoroethyl)plumbanes of the type Pb(C 2 F 5 ) n Ar 4‐ n (Ar = Ph, Tol, Ani; n = 1–3) are easily accessible by treatment of the corresponding arylchloroplumbanes with LiC 2 F 5 . The subsequent treatment with HCl furnishes chloro(pentafluoroethyl)plumbanes. The synthesis of the tris(pentafluoroethyl)plumbate(II) anion is facilitated by treatment of Pb(C 2 F 5 ) 3 Cl with PPh 3 . In addition, formation of Pb(C 2 F 5 ) 4 is achieved starting from Pb(OAc) 4 and is fully characterized by multinuclear NMR spectroscopy and by single crystal x‐ray diffraction of the 1,10‐phenanthroline adduct.
