PURPOSE: To provide a process for fluorination of boron hydrides, which is capable of achieving high levels of fluorination of the borohydride anions, excellent yields and reaction efficiency, high loadings of reactant in the carrier and minimizing yield loss due to byproduct formation. CONSTITUTION: In a liquid phase process for broadly producing compounds of the formula, Ma(RbZcBdHeFy)k where M is a cation having a valence of 1-4, R is a halogen or an alkyl group, Z is C, Si, Ge, Sn, Pb, N, P, As, Sb, or Bi, B is boron, H is hydrogen, a is 1 or 2, b is an integer from 0 to 7, c is an integer from 0 to 1, d is an integer from 5 to 12, e is an integer from 0 to 9, y is an integer from 3 to 12 and is 1, 2 or 3 wherein a multiplied by the valence of M is equal to the integer k or 2 times the integer and the borohydride salt is contacted with fluorine, under conditions for forming the compound, the process comprises a step of effecting the fluorination of the borohydride salt in the presence of a reaction medium having an acidity between that of water and anhydrous HF.
