Scandium trifluoromethanesulfonate, inowanzonzi Scandium(III) triflate, ikemikari yemakemikari ine fomula Sc(SO3CF3)3, munyu unosanganisira scandium cations Sc3+ uye triflate SO3CF3?anions.
Scandium(III) triflate inoshanda zvakanyanya, inoshanda, inodzoreredza uye inogona kushandiswazve acylation catalyst.Iyo yakakosha inokonzeresa yeFriedel-Crafts acylation, Diels-Alder maitiro uye mamwe kabhoni-kabhoni bond-kuita maitiro.Iyo zvakare stereochemically inokonzeresa iyo radical polymerization yeacrylates.Scandium(III) triflate complex ye (4′S,5′S) -2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl]pyridine yakashandiswa sechigadziriso cheasymmetric Friedel-Crafts reaction pakati peinotsiviwa indoles uye methyl (E) -2-oxo-4-aryl-3-butenoates.
