Taupānga
Ka whakamahia te Ytterbium(III) trifluoromethanesulfonate hydrate ki te whakatairanga i te glycosidation o te glycosyl fluorides me te whakakorikori i roto i te whakaritenga o te pyridine me te quinoline derivatives.
Ko te Ytterbium trifluoromethanesulfonate he parenga wai, he maha nga wa e whakamahia ana hei whakakorikori i nga tauhohenga whakahiato waro. Ko te purea ko te nuinga o te ≥98%, ko te ahua he karaihe ma, ko te waahi rokiroki he 2-8℃23. E whakaatu ana i te waikawa kaha i roto i nga wairewa wai, a he maha nga wa e whakamahia ana i roto i nga tauhohenga whakahiato waro e hiahia ana kia kaha te waikawa waikawa
