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,(a) by means of the metal M and in the presence of a hydrogen source for providing hydrogen, or(b) by means of active metal hydrides MHn in the presence of a halogen or alkoxy compound of the 4th and 5th sub group of the periodic table of elements as catalyst,wherein the metal M is selected from Li, Na, K, Rb, Cs, Ca, Sr, and Ba, and wherein the molar ratio between the alkyl methyl ether and the metal M is at least 0.01;

    1 and at most 50;
