Scandium trifluoromethanesulfonate
CAS: 144026-79-9
MF: C3F9O9S3Sc
MW: 492.16
daahirnimo: 98% min
Scandium(III) triflate waa firfircooni aad u firfircoon, hufan, la soo kaban karo oo dib loo isticmaali karo acylation kiciye. Waa kicin muhiim u ah Friedel-Crafts acylation, falcelinta Diels-Alder iyo falcelinta samaynta curaarta kaarboon-kaarboon ee kale. Waxa kale oo ay stereochemical si toos ah u kicisaa polymerization xagjirka ah ee acrylates. Scandium (III) triflate complex of (4′S,5′S) -2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl]pyridine ayaa loo shaqaaleysiiyay kicinta falcelinta Friedel-Crafts asymmetric ee u dhexeeya beddelka in methyldoles (E)-2-oxo-4-aryl-3-butenoates.

Scandium (III) trifluoromethanesulfonate waxaa si weyn loogu isticmaalaa sidii kicinta ee hydrothiolation, la doortay laba-electron hoos u dhigista oxygen by derivatives ferrocene iyo Vinylogous Fridel-farsamada alkylation of indoles iyo pyrrole ee biyaha. Waxay ku lug leedahay isku-darka Mukaiyama aldol oo stereochemically waxay kicisaa polymerization xagjirka ah ee acrylates. Waxay u shaqeysaa sidii kicinta aashitada Lewis waxaana loo isticmaalaa isku dhafka bullvalone iyada oo loo marayo sulfur ylide ah oo xasilan.
