Abstract

Benzosilagermacyclobutene bearing two Ar groups on the germanium atom [Ar = o-(fluorodimethylsilyl)phenyl] undergoes cleavage of the Ge–Si bond with KF in the presence of a cryptand to form Ar3Ge[K+(cryptand)] with α,δ-ambiphilic character consisting of the germyl anion center and the fluorosilyl moieties. In the presence of LiBPh4·3dme or BF3·Et2O, the germylpotassium is converted back into the benzosilagermacyclobutene.
