Inside Cover: The Tris(pentafluoroethyl)stannate(II) Anion, [Sn(C2F5)3]- – Synthesis and Reactivity

The acidic tris(pentafluoroethyl)stannane sweetens the chemistry of tin. The reaction with the reversed polar tri-n-butyltin hydride afforded the highly polarized unsymmetrical distannane. In the reaction with bases, the three electron-withdrawing pentafluoroethyl substituents stabilize the readily transferable tris(pentafluoroethyl)stannate(II) anion, a compound which should not be missed in the cocktail of basic organotin chemistry.
