Scandium (III) triflate jẹ ohun ti nṣiṣe lọwọ lalailopinpin, daradara, imularada ati ayase acylation atunlo. O jẹ ayase pataki fun Friedel-Crafts acylation, awọn aati Diels-Alder ati awọn aati idawọle erogba-erogba miiran. O tun stereochemically ṣe itọsi polymerization ti ipilẹṣẹ ti acrylates. Scandium (III) triflate eka ti (4'S,5'S) -2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl]pyridine ti ni iṣẹ bi ayase fun asymmetric Friedel-Crafts esi laarin ati aropo in methyldo (E) -2-oxo-4-aryl-3-butenoates.
