Abstract
A convenient new preparative method for the unknown class of perfluoroalkyl trifluoroborates K[CnF2n + 1BF3] and perfluoroalkyldifluoroboranes CnF2n 1BF2 (n > 1) is elaborated. The perfluoroalkyl group is introduced into the boric acid ester by using CnF2n + 1MgBr. Treatment with K[HF2] and HF,, re sults in K[CnF2n + 1BF3] which can be defluoridated by AsF5 to the correspo nding boranes CnF2n + 1BF2.
