A composition of matter comprising di-n-butyl-magnesium and dimethylmagnesium, to the exclusion of dialkylmagnesium compounds containing alkyl groups other than n-butyl or methyl, with an n-butyl:methyl aikyl group ratio of about 0.2:1 to about 5:1 which is soluble in aliphatic, cycloaliphatic, and aromatic hydrocarbon solvents is disclosed. The composition is prepared in the substantial absence of oxygen and moisture by the simultaneous or consecutive reactions of methyl and n-butyl halides with metallic magnesium in the presence of the hydrocarbon solvent, followed by separation of the insoluble magnesium chloride and any unreacted magnesium metal from the resulting solution. |
