Abstract / Bemerkung
For (pentafluoroethyl) phenylstannanes, (C2F5)(4-n)SnPhn (n=1-3), and dimethylbis(pentafluoroethyl)stannane, (C2F5)(2)SnMe2, a high yield synthesis was developed by the use of LiC2F5 as a C2F5 transfer reagent. The treatment of these products with gaseous hydrogen chloride or hydrogen bromide afforded (C2F5)(4-n)SnXn (X=Cl, Br; n=1-3) in good yields. The (pentafluoroethyl) stannanes were fully characterized by H-1, C-13, F-19 and Sn-119 NMR, IR spectroscopy and mass spectrometry. The treatment of the (pentafluoroethyl)tin halides (C2F5)(4-n)SnXn with 1,10-phenanthroline (phen) led to the formation of the corresponding octahedrally coordinated complexes [(C2F5)(4-n)SnXn(phen)], the structures of which were elucidated by X-ray diffraction analyses. The bromostannane (C2F5)(3)SnBr reacted with sodium cyclopentadienide to give the (eta(1)-cyclopentadienyl) tris(pentafluoroethyl) stannane, (C2F5)(3)SnCp, for which single-crystal X-ray diffraction analysis could be performed. The coupling constants (1)J(Sn-119, C-13) and (2)J(Sn-119, F-19) of all new stannanes are strongly correlated and sensitive to the substitution pattern at the tin atom. For both coupling constants a negative sign could be assigned.
