Neue Synthesen mit Magnesiumhydrid Teil 1: Hydromagnesierung von α-Olefinen zu Dialkylmagnesiumverbindungen / New Syntheses with Magnesium Hydride Part 1: Hydromagnesiation of α-Olefines to Magnesium-dialkyls

The addition of highly active magnesium hydride to α-olefines, hydromagnesiation, is a well known reaction. The use of cheap magnesium hydride exhibiting a lower reactivity is highly desirable for industrial purposes. In a combination of chemical and mechanical activation the low reactivity of high temperature magnesium hydride could be overcome thereby making a broad variety of magnesium alkyls accessible.

Neue Synthesen von Magnesiumhydrid / New Syntheses of Magnesium Hydride

A very easy and safe way for the production of Ni-doped magnesium hydride is reported. Another process, which is not requiring transition metals (e. g. nickel) has also been found as a means to ameliorate the kinetics of hydrogen uptake. MgH2 itself exerts a catalytic effect on the formation of magnesium hydride from the elements, i. e. by autocatalysis.
