A convenient new preparative method for the unknown class of perfluoroalkyltrifluoroborates K[C n F 2n+1 BF 3 ] and perfluoroalkyldifluoroboranes C n F 2n+1 BF 2 (n > 1) is elaborated. The perfluoroalkyl group is introduced into the boric acid ester by using C n F 2n+1 MgBr. Treatment with K[HF 2 ] and HF aq results in K[C n F 2n+1 BF 3 ] which can be defluoridated by AsF 5 to the corresponding boranes C n F 2n+1 BF 2 .
