Dialkylmagnesium compounds (MgR2, R = C2H5, C4H9 etc.,) have drawn considerable interest in recent years due to their role in commercial polymerization reactions. Herein, we report a thorough account on the reaction intermediates involved in the synthesis of di-n-butylmagnesium from anhydrous magnesium chloride and n-butyllithium. Energy-dispersive X-ray spectroscopy (EDX) and powder X-ray diffraction (PXRD) were used to characterize the products formed in transmetalation reaction and it supports that the Schlenk equilibrium between the nBuMgCl and nBu(2)Mg may be operating during the synthesis of di-n-butylmagnesium from anhydrous magnesium chloride. 1,4-Dioxane was used to shift the Schlenk equilibrium to form soluble 1,4-dioxane adduct of di-n-butylmagnesium and insoluble MgCl2 based product. PXRD was used to study the transformation of 1,4-dioxane adduct of di-n-butylmagnesium to pure di-n-butylmagnesium.
