Process for the preparation of dialkylmagnesium compounds by reaction of magnesium hydride with olefines

摘要

Process for the preparation of dialkylmagnesium compounds by reacting magnesium hydride with an olefin in the presence of halides of subgroups IV to VIII and an ether as reaction medium at a pressure of 1 to 300 bar and in a temperature range of 0 to 200 ° C with the mark, that magnesium hydride is used, which has been activated before and optionally additionally during the reaction with the olefin by grinding to a particle size = 10 μm, and carries out the process without adding complex catalysts.
