Bis(hexamethyldisilazido)magnesium, Mg(HMDS)2 Chemical Properties,Usage,Production

Uses

Magnesium bis(hexamethyldisilazide) is an essential precursor in the synthesis of wide range of diketiminate ligand complexes for rac-lactide polymerization. It can also be used in the synthesis of I^tBu:Mg[N(SiMe₃)₂]₂, where I^tBu = (1,3-di-tert-butylimidazol-2-ylidene), a catalyst for the guanylation reaction of addition of amine to carbodiimide.
