A method for synthesizing an alkali-metal amide comprises the step of charging a reactor vessel with a reaction mixture comprising an alkali metal selected from the group of lithium, sodium, potassium or cesium, an electron carrier, and a disubstituted amine. The disubstituted amine preferably has the formula R,R,NH, wherein R,and R,are independently, the same or different, an alkyl group or &mdash;SiR,, wherein R,is an alkyl group, an aryl group, or an aryl group substituted with an alkyl group. The reaction to form the alkali-metal amide product occurs without the use of a solvent.

Synthetic routes for forming alkali metal substituted borohydride compounds include the step of reacting an alkali metal reagent, a hydrogen donor, and a substituted borane. The reactions proceed without the requirement of specialized handling of alkali metal hydrides associated with prior synthetic processes for the production of alkali metal trisubstituted borohydride compounds. A chemical composition comprises solid potassium tri-sec-butyl borohydride.

Method of synthesis of alkali metal trisubstituted borohydride reagents

The present invention provides a method of reducing copper oxide to improve its acid resistance comprising the step of reacting cupric oxide with a reducing agent selected from the group consisting of morpholine borane, ethylene diamine borane, ethylene diamine bisborane, t-butylamine borane, piperazine borane, imidazole borane, and methoxyethylamine borane to form cuprous oxide.
