Ibisobanuro ku bicuruzwa

Scandium trifluoromethanesulfonate, bakunze kwita triflate ya Scandium (III), ni imiti ivanze na formula Sc (SO3CF3) 3, umunyu ugizwe na casi ya scandium Sc3 + na triflate SO3CF3? anion.
Scandium (III) triflate nigikorwa gikora cyane, gikora neza, gishobora kugarurwa kandi gishobora gukoreshwa na catisale ya acylation. Ni umusemburo wingenzi kuri acylation ya Friedel-Ubukorikori, reaction ya Diels-Alder nibindi bitekerezo bya karuboni-karubone. Ihindura kandi stereochemiki itera polymerisation radical ya acrylates. Scandium (III) triflate complex ya (4′S, 5′S) -2,6-bis [4 ′ - (triisopropylsilyl) oxymethyl-5′-fenyl-1 ′, 3′-oxazolin-2′-yl] pyridine Yakoreshejwe nk'umusemburo wa asimmetric Friedel-Ubukorikori bwerekana hagati ya indoles zasimbuwe na methyl (E) -2-oxo-4-aryl-3-butenoates.

Gusaba

Scandium (III) trifluoromethanesulfonate ikoreshwa cyane nk'umusemburo wa hydrothiolation, guhitamo electroni ebyiri kugabanya ogisijeni ikomoka kuri ferrocene hamwe na vinylogous Fridel-ubukorikori alkylation ya indoles na pyrrole mumazi. Ifite uruhare mukwiyongera kwa Mukaiyama aldol kandi itera stereochemiki itera polymerisation radical ya acrylates. Ikora nka catisale ya Lewis kandi ikoreshwa muri synthesis ya bullvalone ikoresheje sulfure ylide itajegajega.
