Abstract

Abstract Hydrocarbon soluble organo-magnesium complex of the formula (R.sub.2 'Mg).sub.m . [(RO).sub.a M].sub.n wherein R is a hydrocarbyl group or ##STR1## wherein R 2 is a hydrocarbyl group. R' is a primary alkyl group having 1 to 25 carbon atoms, or phenyl group, or mixture thereof, M is a group IIA or group IIIA metal and a is 2 or 3, and m and n are numbers such that the ratio of m/n is about one or greater. 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 an oxygen containing metal compound of the formula (RO) a M wherein R, M and a are as defined. The oxygen containing metal 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 M ratios of between about 1:2 to about 20:1 and hydrocarbon solubility.
