General description

Di-n-butylmagnesium solution is a useful reagent for the synthesis of organomagnesium compounds.

Application

Di-n-butylmagnesium solution can be used as a reagent for the deprotection of aromatic and aliphatic benzyl thioethers to synthesize corresponding benzylthiols in the presence of titanocene dichloride[1]. It can also be used as a catalyst to synthesize enantioenriched nitrogen-containing heterocyclic derivatives by the asymmetric ring-opening reaction of aziridines with substituted tetrazoles in the presence of chiral ligand[2].

A magnesium-catalyzed asymmetric ring-opening reaction of aziridines with substituted tetrazoles is reported. The current protocol proceeds smoothly and gives the corresponding desymmetrization products in high yields and good enantioselectivities.

    Terrible product - consistently contaminated with THF

    Contains THF, should be advertised as Mg(nBu)2(THF)2 for clarity.
