ABSTRACT:
A method for the preparation of dialkylmagnesium compounds is disclosed, wherein magnesium hydride is reacted with an olefin in the presence of a halide of sub-groups IV to VIII of the Periodic Table and in the presence of an ether as reaction medium at a temperature of about between 1 to 300 bar and in a temperature range of about 0.degree. to 200.degree. C. According to the disclosed invention, the magnesium hydride is activated by grinding to a particle size of .ltoreq.10 .mu.m and the method is carried out in the absence of complex catalysts. The grinding of the magnesium hydride takes place prior to the reaction with the olefin, but may also be conducted during the reaction.
