Scandium trifluoromethanesulfonate, e atisang ho bitsoa Scandium(III) triflate, ke motsoako oa lik'hemik'hale o nang le foromo ea Sc (SO3CF3)3, letsoai le nang le scandium cations Sc3+ le triflate SO3CF3? anions.
Scandium(III) triflate ke sesebelisoa sa acylation se sebetsang haholo, se sebetsang hantle, se ka khutlisoang hape se ka sebelisoang hape. Ke mohloli oa bohlokoa bakeng sa Friedel-Crafts acylation, Diels-Alder reactions le tse ling tsa carbon-carbon bond-forming reactions. E boetse e thusa ka mokhoa o ts'oanelang ho etsa polymerization e matla ea li-acrylates. Scandium(III) triflate complex ea (4′S,5′S) -2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl]pyridine E sebelisitsoe e le sesosa sa karabelo ea asymmetric Friedel-Crafts lipakeng tsa li-indoles tse emisitsoeng le methyl (E) -2-oxo-4-aryl-3-butenoates.

Scandium(III) trifluoromethanesulfonate e sebelisoa haholo e le sesosa sa hydrothiolation, ho khetha ho fokotsa oksijene ea li-electron tse peli ka lihlahisoa tsa ferrocene le vinylogous Fridel-crafts alkylation ea indoles le pyrrole metsing. E kenella ho tlatsetso ea Mukaiyama aldol mme e susumetsa ka mokhoa o ts'oanang ho etsa polymerization e matla ea li-acrylates. E sebetsa joalo ka Lewis acid catalyst mme e sebelisoa ha ho etsoa bullvalone ka ylide e tsitsitseng ea sebabole.
