Description

Liquid

The pure substance is a waxy solid. Commercially, it is marketed as solution inheptane. Di-n-butylmagnesium solution is a useful reagent for the synthesis of organomagnesium compounds.

Contains up to 1 wt. % Triethylaluminum as a viscosity reducer. stable under normal temperature and pressure, sensitive to light. contact with water releases flammable gas.

Di-n-butylmagnesium Use and Manufacturing

Uses

Intermediates

Electrochemically inactive [Mg2(μ-Cl)3.6THF][C2H5AlCl3] crystal may be obtained from an electrolyte composed of Di-n-butylmagnesium and ethylaluminum dichloride. Di-n-butylmagnesium may be used in the carbon metallation of α-olefins. A study reports the possible use of the organometallic compound in the intercalation of magnesium and zinc into the layers of TiS2or WO2Cl2. Interaction of lithium alkoxide with di-n-butylmagnesium was investigated.
