Application

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 ItBu:Mg[N(SiMe3)2]2, where ItBu = (1,3-di-tert-butylimidazol-2-ylidene), a catalyst for the guanylation reaction of addition of amine to carbodiimide.

Magnesium secondary batteries are promising candidates for large-scale energy storage systems with high safety, because of the dendrite-free electrodeposition of the magnesium anode. However, the search for available cathode materials remains a significant challenge, hindering their development. In this work
