    • A low viscosity liquid solution is described, comprising(a) a hydrocarbon-soluble dialkylmagnesium compound of 4 to 20 carbon atoms per molecule(b) a solvent selected from the group consisting of aliphatic, alicyclic, and aromatic hydrocarbons of 5 to 20 carbon atoms, and(c) an organometallic additive selected from the group consisting of R.sub.3 Ga, R.sub.3 In, and RLi, in which R is C.sub.1 -C.sub.12 alkyl or C.sub.5 -C.sub.7 cycloalkyl.Also disclosed is a method of preparing such a solution by in situ generation of the dialkylmagnesium compound via the reaction between metallic magnesium and the appropriate alkyl halide in the presence of both the solvent and the organometallic additive.
