Scandium trifluoromethanesulfonate, nke a na-akpọkarị Scandium(III) triflate, bụ ngwakọta kemịkalụ nwere usoro Sc (SO3CF3) 3, nnu nke nwere scandium cations Sc3+ na triflate SO3CF3?anions.
Scandium(III) triflate bụ ihe na-arụsi ọrụ ike, na-arụ ọrụ nke ọma, nke a na-enwetaghachi na nke a na-emegharị acylation.Ọ bụ ihe mkpali dị mkpa maka Friedel-Crafts acylation, mmeghachi omume Diels-Alder na mmeghachi omume mmekọ carbon-carbon ndị ọzọ.Ọ na-ejikwa stereochemically na-akwalite radical polymerization nke acrylates.Scandium (III) triflate complexes nke (4′S,5′S)-2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl]pyridine ejirila ya mee ihe dị ka ihe na-akpali akpali maka mmeghachi omume Friedel-Crafts asymmetric n'etiti indoles nọchiri anya na methyl (E) -2-oxo-4-aryl-3-butenoates.
