Hydrocarbon soluble organo-magnesium complex of the formula n n (RR'Mg).sub.m ยท (R.sub.3 Al).sub.n n n wherein R is a primary, secondary or tertiary alkyl group having from 1 to 25 carbon atoms. R' is a primary alkyl group having 1 to 25 carbon atoms, or phenyl group, or mixture thereof, and m and n are numbers such that the ratio of m/n is about one or greater. n These complexes are prepared by reacting magnesium metal with a primary alkyl halide or phenyl halide in the presence of a hydrocarbon solvent and adding thereto a metal organo-aluminate of the formula R 4 AlM wherein R is as defined and M is sodium, potassium or lithium. The metal organo-aluminate compound functions as a solubilizing agent for organo-magnesium compounds which are normally only slightly soluble in hydrocarbon media. These complexes are characterized by very low halide content, lack of ether contamination, magnesium to aluminum ratios of between about 1:2 to about 20:1, and hydrocarbon solubility. |
