Abstract:
The invention relates to a method for producing organometallic compounds RMn (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 which method 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.

Claim (Index 8):
A method for producing organometallic compounds R n M of the alkali or alkaline earth elements, where R=alkyl residue with 2 to 18 C atoms, characterized in that an \u03b1-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 consistips of dimethyl ether, methyl ethyl ether, methyl propyl ether, methyl butyl ether, methyl pentyl ether, methyl cyclopentyl ether, methyl hexyl ether, by means of (i) the metal M and in the presence of a hydrogen source for providing hydrogen, or (ii) by means of active metal hydrides in the presence of a halogen or alkoxy compound of the 4 th  and 5 th  sub group of the PSE as catalyst, wherein the molar ratio between alkyl methyl ether and metal M is at least 0.01:1 and at most 50:1, characterized in that the active metal hydrides are produced in situ and in the presence of finely dispersed metal M 2  with a mean particle size D 50  of 0.01 to 100 \u03bcm and a source for hydrogen, wherein\n M 2 =an element of the 3rd main group of the PTE selected from the group consisting of B, Al, Ga, In; n=1 or 2, corresponding to the valence of the metal M.
