  • Synthesis of amine boranes and polyhedral boranes
    Patent number: 10179795
    Abstract: 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.
    Type: Grant
    Filed: February 3, 2015
    Date of Patent: January 15, 2019
    Assignee: THE CURATORS OF THE UNIVERSITY OF MISSOURI
    Inventors: Alexander Valentinovich Safronov, Satish Subray Jalisatgi, Marion Frederick Hawthorne
