Abstract
The research area of perfluoroalkylsilanes is still in its infancy. Although there are already many examples of difluorotriorganylsilicates, the first example of a completely characterized trifluorotriorganylsilicate is presented, the dianion [Si(C2F5)(3)F-3](2-). The strongly electron-withdrawing influence of the pentafluoroethyl groups appears to be a fundamental cause of the stability of this compound. This dianion is also the first structurally characterized example of a tris(pentafluoroethyl)silicon compound. The synthesis and complete characterization of [PPh4](2)[Si(C2F5)(3)F-3] and [PPh4][Si(C2F5)(3)F-2] along with the precursor [H(OEt2)(2)][Si(C2F5)(3)F-2] was achieved from SiCl4 and LiC2F5.
