Abstract

The relatively stable white solid tris(pentafluorophenyl)boron has been prepared in high yield from boron trichloride and pentafluorophenyllithium using pentane as a solvent. It shows strong acceptor properties towards the Lewis bases: ammonia, trimethylamine, triphenylphosphine, and pyridine. With excess of pentafluorophenyllithium the salt lithium tetrakis(pentafluorophenyl)borate is formed; the water-soluble borate precipitates the tetraethylammonium and potassium derivatives from concentrated aqueous solutions.

    The key initial step to the discovery of these applications is the synthesis of the borane itself, for which two main strategies have been reported and are repeatedly used. Massey prepared B(C6F5)3 from Grignard reagent C6F5MgBr with BCl3, a later patent in 1994 reported a lithiation procedure with LiC6F5.9,19 It must be noted that extreme caution is required in the latter synthesis, due to a risk of explosion above − 40 °C arising from the decomposition to benzyne derivatives via elimination of lithium fluoride, a risk that is present in aryl derivatives with ortho-fluorines.20
