  • Alkali metal-containing, organometallic products
    Patent number: 3932545
    Abstract: An alkali metal-containing, organometallic product, which is hydrocarbon-soluble, is prepared by reacting an organo-alkali metal reactant in which the alkali metal atom is bonded to a carbon atom, e.g. cyclohexyl-lithium, with a di(organooxy)-alkaline earth metal reactant, e.g. di-n-butoxy-magnesium, in an organic solvent at about -20.degree. to +120.degree.C. The organo-alkali metal reactant can be prepared by reacting an organo halide with an alkali metal, and this can be done in situ, i.e. in the presence of the di(organooxy)-alkaline earth metal reactant. The organometallic product has approximately the same chemical reactivity as the organo-alkali metal reactant from which it is prepared, but is more soluble in hydrocarbon solvents.
