Abstract

Organometallic amide compositions and processes for preparing the same, for example, by: reacting an alkali metal, alkali metal hydride, or alkali metal amide with a substituted amine in the absence of an electron carrier; reacting an alkali metal with a substituted amine in the presence of an electron carrier in a hydrocarbon solvent; distilling a composition which includes an alkali metal amide and a reduced electron carrier to recover the alkali metal amide; reacting an alkali metal with a substituted amine in the presence of an alkyl halide; and reacting a substituted amine capable of reacting with an alkali metal to form a hydrocarbon insoluble alkali metal amide with an alkali metal in the presence of a substituted amine capable of reacting with an alkali metal to form a hydrocarbon soluble alkali metal amide.
