Abstract
The invention relates to lithium alkyl aluminates according to the general formula Li[AlR] and to a method for preparing same, starting from LiAlHand RLi in an aprotic solvent. The invention also relates to compounds according to the general formula Li[AlR] which can be obtained using the claimed method, and to the use thereof. The invention also relates to the use of a lithium alkyl aluminate Li[AlR] as a transfer reagent for transferring at least one radical R to an element halide or metal halide and to a method for transferring at least one radical R to a compound E(X)for preparing a compound according to the general formula E(X)R, where E=aluminium, gallium, indium, thallium, germanium, tin, lead, antimony, bismuth, zinc, cadmium, mercury, or phosphorus, X=halogen, q=2, 3 or 4, and p=1, 2, 3 or 4. The invention also relates to compounds which can be obtained using such a method, to the use thereof, and to a substrate which has an aluminium layer or a layer containing aluminium on one surface.
