This invention provides a method for producing organometallic compounds RnM (M=alkali or alkaline earth element, R=alkyl residue) where n=valence of the metal M and R=alkyl residue with 2 to 18 C atoms. In the method of this invention, an olefin is hydrometalated in an alkyl methyl ether, or in a solvent mixture containing an alkyl methyl ether, by means of the metal M and in the presence of a hydrogen source and in the presence of a transition metal catalyst, wherein the molar ratio between alkyl methyl ether and metal M is at least 0.01:1 and at most 50:1.
A method for producing organometallic compounds RnM of the alkali or alkaline earth elements, where n=valence of the metal M and R=alkyl residue with 2 to 18 C atoms, characterized in that an α-olefin is hydrometalated in an aprotic and anhydrous liquid phase comprising an alkyl methyl ether wherein said alkyl methyl ether is selected from the group consisting of dimethyl ether, methyl ethyl ether, methyl propyl ether, methyl butyl ether, methyl pentyl ether, methyl cyclopentyl ether, and methyl hexyl ether,
