Codsiga

Ytterbium(III) trifluoromethanesulfonate hydrate waxaa loo isticmaalaa si kor loogu qaado glycosidation of glycosyl fluorides iyo sida kicinta diyaarinta pyridine iyo quinoline derivatives.

Ytterbium trifluoromethanesulfonate waxay leedahay iska caabbinta biyaha waxaana badanaa loo isticmaalaa in lagu kiciyo falcelinta isku-dhafka dabiiciga ah ee kala duwan. Nadiifinta badanaa waa ≥98%, muuqaalku waa crystal cad, iyo xaalada kaydinta waa 2-8℃‌23. Waxay soo bandhigtaa aysidh xoog leh xalal aqueous waxaana inta badan loo isticmaalaa falcelinta synthesis organic taas oo u baahan catalysis xoog leh
