标 题:Method of synthesis of lithium substituted borohydride reagents and method of synthesis of reactive lithium hydride
发明人：BURKHARDT ELIZABETH R; SUTTON CHRISTOPHER P; BRUENING JOERG; ROUDA DAVID F
权利人:MINE SAFETY APPLIANCES CO
摘要: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.
