Synthesis
Dibutylmagnesium can be obtained by reaction of butyllithium with magnesium butylchloride and subsequent addition of magnesium 2-ethylhexanoate.[3] The compound can also be prepared by hydrogenation of magnesium, followed by reaction with 1-butene.[4] It is also possible to prepare dibutylmagnesium using 2-chlorobutane, magnesium powder, and n-butyllithium.[5]
Use
Dibutylmagnesium is used as a convenient reagent for the preparation of organomagnesium compounds.[3][6][7]
