Beschreibung

Allgemeine Beschreibung

Magnesium bis(trifluoromethanesulfonimide) (Mg(TFSI)₂) is a strong magnesium Lewis acid. It is used as a catalyst in organic synthesis. For instance, it is used in the synthesis of dihydropyrazoles by reaction of nitrilimines with alkenes. Additionally, Mg(TFSI)₂ salt is also useful for ionic conductivity studies, transference number measurements, and electrochemical properties of gel polymer electrolyte (GPE) systems.

Magnesium bis(trifluoromethanesulfonimide), also known as magnesium triflimide, can be used as an inorganic catalyst in various organic reactions, including acetylation of phenols and alcohols, aminolysis of lactones with amines, [2 + 2] cycloadditions of siloxy-alkynes with carbonyl compounds, cycloisomerization of 1,6-dienes, Friedel-Crafts acylation, and for the synthesis of coumarins.

Anwendung

• Rechargeable Battery Research: Utilized in the study of rechargeable Mg-ion batteries, Magnesium bis(trifluoromethanesulfonimide) serves as a model anode material, providing significant insights into atomistic and mesoscale mechanisms that could revolutionize battery development and application (Kravchyk et al., 2018).
