Abstract / Bemerkung
Syntheses of salts containing the tris(pentafluoroethyl) stannate(II) ion, [Sn(C2F5)(3)](-), were achieved through deprotonation of the corresponding stannane, HSn(C2F5)(3), as well as by direct pentafluoroethylation of SnCl2 with LiC2F5. The electron-withdrawing substituents have substantial influence on the stability and reactivity of the anion as documented by its treatment with main group halides. Alkyl halides (R-X) underwent nucleophilic substitutions to afford RSn(C2F5)(3), whereas Si, Ge, Sn, P halides gave rise to oxida-tion processes yielding hypervalent [SnX2(C2F5)(3)](-) salts (X = Cl, Br, I). Moreover the unsymmetrical distannane, nBu(3)SnSn(C2F5)(3), was disclosed as an alternative precursor for the Sn(C2F5)(3) moiety. Although neither the solid state structure nor its spectra in alkane solution reveal unexpected peculiarities, unusual dissociation of the compound in coordinating solvents into [nBu(3)Sn(D)(n)](+) and [Sn(C2F5)(3)](-) ions was observed.
