Ingcaciso yeMveliso

Kwi-organic chemistry, i-triflate, eyaziwa ngegama elicwangcisiweyo elithi trifluoromethanesulfonate, liqela elisebenzayo elinefomula CF₃SO₃−.Iqela le-triflate lisoloko limelwe ngu- −OTf, ngokuchaseneyo no- −Tf (triflyl).Umzekelo, i-n-butyl triflate inokubhalwa njenge-CH₃CH₂CH₂CH₂OTf.

Isicelo

I-Lanthanum trifluoromethanesulfonate isetyenziswe kwi-Aldol reaction ye-silyl enol ethers kunye ne-aldehydes.Yinto esebenzayo ye-Baylis-Hillman reaction.Ikwabangela ukongezwa kukaMichael kwi-methyl vinyl ketone emanzini.

I-Lewis acid ekwazi ukumelana namanzi esetyenziswe kwi-Aldol reaction ye-silyl enol ethers ene-aldehydes.
