Abstract : A method is described for preparing a mixture of decarborane-14 and an alkyl-substituted decaborane-14 which comprises admixing an ethereal solution of nonaborane-14 ions with an alkaliboron halide at a temperature from 20 C to 30 C and at pressure from atmospheric pressure to 400 psig and a method of preparing decaborane-14 which comprises preparing an ethereal solution of nonaborane-14 by a reaction in an ethereal solution of an alkali metal borohydride with an excess of pentaborane-9 at temperature from 20 C to 30 C and admixing this ethereal solution of nonaborane-14 ions with diborane-6 at a temperature from 20 C to 30 C and at a pressure of at least 50 psig. Such compounds are useful as precursor compounds for the synthesis of important carborane derivatives, such as n-hexylcarborane (a catalyst for rocket propellants) and high-temperature-resistant carborane/siloxane polymers.
