Tetrabutylammonium tetrafluoroborate and tetrabutylammonium borohydride were reacted in an attempt to prepare fluorinated borohydride anions via exchange reactions.  These reactions were performed by melting and stirring the reactants at 130 �C in a vacuum.  The stoichiometric ratio of the reactants was varied but the highest yield of a fluorinated boron-containing anion was obtained with a 1:1 ratio.  The boron-containing anion reacts readily with THF at room temperature.  The 11B NMR, 19F NMR, and 1H NMR spectra for this fluorinated boron-containing anion and the product of its reaction with THF will be reported.
