Purity: 98% min
Scandium (III) triflate yog ib tug nquag nquag, ua tau zoo, rov qab zoo thiab rov siv dua acylation catalyst. Nws yog ib qho tseem ceeb catalyst rau lub frifel-crafts acylation, diels-alervation thiab lwm yam carbon-carbon brecing kev tawm tsam. Nws tseem stereochemically catalenyzes lub radical polymerization ntawm acrylates. Scandium (III) Triflate complex ntawm (4's, 5's) -2,6-pis [4'-PYenyPr-1 '-Oxazolin-2'-YL] Pyridine tau ua haujlwm ua cov tshuaj tua hluav taws xob ua rau cov khoom siv asymmetric ntawm cov khoom lag luam thiab methyl (e)-oxo-4-aryl-3-butenoates.

Scandium (III) Trifluoromometoromethanesulfonate yog dav siv ua catallocene derivatives thiab vinylogous feridor-crafts alkylation ntawm indoles thiab pyrrole nyob rau hauv dej. Nws koom nrog hauv Mukaiyama aldol ntxiv thiab cov kev sib txuas lus catalenyzes lub radical polymerization ntawm acrylates. It acts as a Lewis acid catalyst and used in the synthesis of bullvalone via a stabilized sulfur ylide.
