Isicelo

I-YTterbium (III) I-Trifluoromeselasusulfonate Hydrate isetshenziselwa ukukhuthaza ukugqugquzela i-glycosyl fluorides kanye ne-catalyst lapho kulungiswa ama-pyridine kanye nama-qurivatives we-quinoline.

I-Ytterbium Trifluoromeselasulfonate inokumelana kwamanzi futhi ivame ukusetshenziselwa ukulimaza ukuguquguquka okuhlukahlukene okuhlukahlukene kwe-organic. Ubumsulwa buvame ≥98%, ukubukeka ku-crystal emhlophe, futhi isimo sesitoreji singu-2-8 ℃ 23. Ibonisa i-acidity eqinile kwizixazululo zamanzi futhi ivame ukusetshenziswa ekuhlolweni kwe-organic synthesis ezidinga ukucasuka okunamandla kwe-acid
