  • Method of synthesis of lithium substituted borohydride reagents and method of synthesis of reactive lithium hydride
    Patent number: 6268537
    Abstract: A synthetic route for forming lithium trisubstituted borohydride compounds comprises the step of reacting a processed lithium hydride reactant with a trisubstituted borane wherein the reaction is maintained for a period of time in a temperature range of approximately 15° C. to approximately 42° C. A method of synthesizing LiH comprises the step of reacting an alkyl lithium (for example, n-butyl lithium) with hydrogen in the presence of tetrahydrofuran. The reaction temperature is preferably maintained in the range of approximately −78° C. to approximately 25° C.
    Type: Grant
