Abstract
Abstract The action of an ethereal solution of methylmagnesium iodide on cobaltous chloride, in a molar ratio of 2:1, results in reduction of the cobaltous chloride to zero-valent cobalt complexed with magnesium halide. When a large excess of methylmagnesium halide is used, the product is a colloidal suspension of particles, suggested to have the composition Co[CH3MgI]2, containing zero-valent but non-ferromagnetic cobalt and heavily solvated with molecules of ether. A complex mixture of hydrocarbons is evolved on formation of the colloidal suspension, and, on the assumption that two methyl radicals are liberated per molecule of cobaltous chloride, the observed hydrocarbons can be accounted for both qualitatively and quantitatively by means of a series of free-radical reactions.
