Incazelo Yomkhiqizo

I-Ytterbium trifluoromethanesulfonate

I-CAS: 252976-51-5

MF: C3H2F9O10S3Yb

MW: 638.26

Ubumsulwa: 98%min

Kuyi-catalyst ye-Lewis acid engavimbeli amanzi, evame ukusetshenziswa ekuhlanganiseni kwebhodwe elilodwa le-β-lactam ene-nucleophilic elawulwa yi-stereoconfiguration yama-radicals mahhala.

Isicelo

I-Ytterbium(III) trifluoromethanesulfonate hydrate isetshenziselwa ukukhuthaza i-glycosidation ye-glycosyl fluorides nanjenge-catalyst ekulungiseleleni okuphuma kokuphuma kwe-pyridine ne-quinoline.

I-Ytterbium trifluoromethanesulfonate inokumelana namanzi futhi ivamise ukusetshenziselwa ukuvuselela ukusabela okuhlukahlukene kwe-organic synthesis. Ukuhlanzeka kuvame ukuba ngu-≥98%, ukubonakala kuyikristalu emhlophe, futhi isimo sokugcina singu-2-8℃‌23. Ibonisa i-asidi eqinile ezixazululweni ezinamanzi futhi ivame ukusetshenziswa ekuphenduleni kwe-organic synthesis edinga i-acid catalysis eqinile.
