SYNTHESIS OF AMINE BORANES AND POLYHEDRAL BORANES

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.

1. A method for synthesizing mixtures of salts of polyhedral boranes, comprising:
combining a methyltriethylammonium halide with an alkali metal tetrahydroborate in a reaction mixture; reacting the methyltriethylammonium halide and the alkali metal tetrahydroborate to form a methyltriethylammonium tetrahydroborate intermediate and an alkali metal halide; and pyrolizing the methyltriethylammonium tetrahydroborate intermediate to produce a product mixture comprising methyltriethylammonium decahydrodecaborate and methyltriethylammonium dodecahydrododecaborate.
