Daim ntawv thov

Ytterbium (III) trifluoromethanesulfonate hydrate yog siv los txhawb glycosidation ntawm glycosyl fluorides thiab ua ib qho catalyst hauv kev npaj ntawm pyridine thiab quinoline derivatives.

Ytterbium trifluoromethanesulfonate muaj dej tsis kam thiab feem ntau yog siv los ua kom muaj ntau yam kev sib txuas ntawm cov organic. Lub purity feem ntau yog ≥98%, qhov tsos yog dawb siv lead ua, thiab qhov chaw cia yog 2-8 ℃ 23. Nws pom muaj zog acidity nyob rau hauv aqueous daws thiab feem ntau yog siv nyob rau hauv cov organic synthesis tshuaj uas yuav tsum tau muaj zog acid catalysis
