Synthesis of amine borane and polyhedral borane

摘要

The present invention relates in general to a method for the synthesis and purification of 1) the polyhedral borane decahydrodecaborate and dodecahydrododecaborate anions and their salts and 2) amines and amine boranes. The organoammonium halide is combined with alkali metal tetrahydroborate to form organoammonium tetrahydroborate, which upon pyrolysis provides organoammonium decahydrodecaborate and organoammonium dodecahydrododecaborate.
