In 2022,Suzuki, Itaru; Takenaka, Yuya; Morishita, Yoshitaka; Shibata, Ikuya published an article in Chemistry Letters. The title of the article was 《One-step Preparation of N-Unprotected Aziridines from 2H-Azirines by Addition of Ketene Silyl Acetals Catalyzed by Lewis Acids》.Safety of Indium(III) bromide The author mentioned the following in the article:
The nucleophilic addition of ketene silyl acetals 2 into 2H-azirines 1 proceeded in the presence of Lewis acids such as InX3 or Sc(OTf)3 to give N-unprotected aziridines 3. The mild Lewis acidity of the catalyst is important for the achievement of this coupling. The generated aziridine 3 could then be transformed into either oxazolines or γ-amino carbonyls. In addition to this study using Indium(III) bromide, there are many other studies that have used Indium(III) bromide(cas: 13465-09-3Safety of Indium(III) bromide) was used in this study.
Indium(III) bromide(cas: 13465-09-3) is used as a catalyst to produce dithioacetals when unactivated alkynes react with thiols and fields such as optics and microelectronics that utilize semiconductor technology have wide uses for indium in high-performing solar cells.Safety of Indium(III) bromide
