Abstract
A composition of matter comprising di-n-butylmagnesium and diethylmagnesium with a n-butyl:ethyl alkyl group ratio of about 0.25:1 to about 4:1 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 ethyl 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.
