Kumakhemikhali wezinto eziphilayo, i-triflate, eyaziwa nangokuthi igama elihlelekile i-trifluoromethanesulfonate, iyiqembu elisebenzayo elinefomula ethi CF₃SO₃−.Iqembu le-triflate livamise ukumelwa ngu-−OTf, ngokungafani no-−Tf (triflyl).Isibonelo, i-n-butyl triflate ingabhalwa ngokuthi CH₃CH₂CH₂CH₂OTf.

I-Lanthanum trifluoromethanesulfonate isetshenziswa ekuphenduleni kwe-Aldol kwe-silyl enol ethers ene-aldehydes.Kuyi-catalyst esebenzayo yokusabela kwe-Baylis-Hillman.Iphinde ikhuthaze izengezo zikaMichael ku-methyl vinyl ketone emanzini.
I-Lewis acid ekwazi ukumelana namanzi esetshenziswa ekuphenduleni kwe-Aldol kwe-silyl enol ethers ene-aldehydes.
Isevisi esingayinikeza
1) Inkontileka esemthethweni ingasayinwa
2) Isivumelwano sokugcinwa kuyimfihlo singasayinwa
3) Isiqinisekiso sokubuyiselwa imali sezinsuku eziyisikhombisa
Okubaluleke nakakhulu: asikwazi ukunikeza umkhiqizo kuphela, kodwa isevisi yesixazululo sobuchwepheshe!
