Dibutylmagnesium is an organometallic chemical compound of magnesium. Its chemical formula is C
₈H
₁₈Mg.^[1] Dibutylmagnesium is a chemical compound from the group of organomagnesium compounds. The pure substance is a waxy solid. Commercially, it is marketed as solution in heptane.^[2]

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.^[1] It is also possible to prepare dibutylmagnesium using 2-chlorobutane, magnesium powder, and n-butyllithium.^[4]

Use

Dibutylmagnesium is used as a convenient reagent for the preparation of organomagnesium compounds.^[3]^[2]^[5]
