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. 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.

Other Notes

  • Contains up to 1 Wt% Triethylaluminum as a Viscosity Reducer
  • This material can vary from light to very dark in appearance. These differences in color will have no effect on use.
  • May contain up to 3% THF
