Scandium(III) triflate babban aiki ne, mai inganci, mai iya murmurewa da sake amfani da kuzarin acylation. Yana da mahimmanci mai kara kuzari ga Friedel-Crafts acylation, Diels-Alder halayen da sauran halayen haɗin gwiwar carbon-carbon. Har ila yau, stereochemically yana haifar da radical polymerization na acrylates. Scandium (III) triflate hadaddun (4′S,5′S) -2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl]pyridine an yi amfani da shi azaman mai kara kuzari ga asymmetric Friedel-Crafts dauki tsakanin da maye gurbin in methyldo (E) -2-oxo-4-aryl-3-butenoates.
