Scandium trifluoromethanesulfonate, oo caadi ahaan loo yaqaan Scandium (III) triflate, waa isku dhaf kiimiko ah oo leh caanaha Sc (SO3CF3) 3, milix ka kooban scandium cations Sc3+ iyo triflate SO3CF3? anions.
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 oo ah (4′S,5′S)-2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl]pyridine ayaa loo shaqaaleysiiyay sidii kicinta falcelinta asymmetric Friedel-Crafts ee u dhexeeya indoles la beddelay iyo methyl (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 ferrocene derivatives 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 xasilan.
