ʻO Scandium trifluoromethanesulfonate, i kapa ʻia ʻo Scandium(III) triflate, he hui kemika me ke ʻano Sc(SO3CF3)3, he paʻakai i loaʻa nā scandium cations Sc3 + a me triflate SO3CF3? anions.
ʻO Scandium (III) triflate he mea hoʻoikaika ikaika, kūpono, hiki ke hoʻihoʻi a hoʻohana hou ʻia acylation catalyst. He mea hoʻoikaika koʻikoʻi ia no ka Friedel-Crafts acylation, Diels-Alder reactions a me nā hopena hoʻopaʻa kalapona kalapona ʻē aʻe. Hoʻopiʻi stereochemically ia i ka polymerization radical o nā acrylates. Scandium(III) triflate complex o (4′S,5′S)-2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl] pyridine ua hoʻohana ʻia ma ke ʻano he catalyst no ka hopena Friedel-Crafts asymmetric ma waena o nā indoles i pani ʻia a me ka methyl (E) -2-oxo-4-aryl-3-butenoates.

Hoʻohana nui ʻia ʻo Scandium (III) trifluoromethanesulfonate ma ke ʻano he catalyst i ka hydrothiolation, koho ʻelua-electron hōʻemi o ka oxygen e nā ferrocene derivatives a me vinylogous Fridel-crafts alkylation o indoles a me pyrrole i ka wai. Ua komo i loko o ka Mukaiyama aldol hoʻohui a stereochemically catalyzes ka radical polymerization o acrylates. Hana ʻo ia ma ke ʻano he mea hoʻohuihui Lewis a hoʻohana ʻia i ka synthesis o ka bullvalone ma o ka sulfur ylide paʻa.
