Abstract / Bemerkung
The tin-tin bond cleavage of hexaorganodistannanes by nucleophiles is a long-known reaction and widely used for stannate formation or stannyl group transfer. Herein, we detail our experiments to provide analytical evidence for the existence of the reasonably stable anionic complexes [XSn(C2F5)(3){Sn(C2F5)(3)}](-) (X=Cl, Br, I, Sn(C2F5)(3)) derived from hexakis(pentafluoroethyl)distannane. NMR investigations at low temperature lend further mechanistic insights. Thus, by detection of the imposing ion [Sn(C2F5)(3){Sn(C2F5)(3)}(2)](-), one can surmise that the chemistry of Sn-2(C2F5)(6) has more in common with the isolobal iodine than with classical distannanes.
