Abstract

Tris[3,5-bis(trifluoromethyl)phenyl]borane (1, BArF(18)), has been synthesised on a practical scale for the first time. According to the Gutmann-Beckett method it is a more powerful Lewis acid than B(C(6)F(5))(3). It forms a 'frustrated Lewis pair' with 2,2,6,6-tetramethylpiperidine which cleaves H(2) to form a salt containing the novel anion [μ-H(BArF(18))(2)](-).
