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.
一种含有碱金属的有机金属产物,其可溶于烃类溶剂,是通过在有机溶剂中将含有碳原子的碱金属有机反应物与二(有机氧基)碱土金属反应物反应制备而成,例如环己基锂与二正丁氧基镁,在约-20°C至+120°C的温度下反应。有机碱金属反应物可以通过有机卤化物与碱金属反应制备,而且这可以在原地完成,即在二(有机氧基)碱土金属反应物的存在下进行。这种有机金属产物与其制备的碱金属有机反应物具有大致相同的化学反应性,但在烃类溶剂中更易溶解。
