I-Scandium trifluoromethanesulfonate, edla ngokubizwa ngokuba yi-Scandium (III) triflate, i-chemical compound ne-formula Sc (SO3CF3) 3, ityuwa equka i-scadium cations Sc3 + kunye ne-triflate SO3CF3?iianions.
I-Scandium(III) triflate sisixhobo esisebenza ngokugqithisileyo, esisebenzayo, esinokubuyiselwa kunye nesisebenziseka kwakhona kwi-acylation catalyst.I-catalyst ebalulekileyo ye-acylation ye-Friedel-Crafts, i-Diels-Alder reactions kunye nezinye ii-carbon-carbon bond-forming reactions.Kwakhona i-stereochemically catalyzes i-radical polymerization ye-acrylates.I-Scandium(III) triflate complex ye (4′S,5′S)-2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl]pyridine isetyenziswe njenge-catalyst ye-asymmetric Friedel-Crafts reaction phakathi kwe-indoles efakwe endaweni kunye ne-methyl (E) -2-oxo-4-aryl-3-butenoates.

I-Scandium (III) i-trifluoromethanesulfonate isetyenziswa ngokubanzi njenge-catalyst kwi-hydrothiolation, ekhethiweyo yokunciphisa i-electron ezimbini ze-oksijini ngokuphuma kwe-ferrocene kunye ne-vinylogous Fridel-crafts alkylation ye-indoles kunye ne-pyrrole emanzini.Ibandakanyeka kwi-Mukaiyama aldol yokongeza kwaye i-stereochemically icatalyzes i-radical polymerization ye-acrylates.Isebenza njengecatalyst ye-Lewis acid kwaye isetyenziswa ekudibaneni kwe-bullvalone nge-ylide yesulfure ezinzileyo.
