I-Ytterbium (III) i-Trifluoromethanesulfonate Hydrate (CAS: 54761-04-5) isebenza njenge-catalyst kwi-organic synthesis ye-heterocycles.Ikwasebenza njengeasidi yeLewis kwiintlobo ezahlukeneyo zokusabela kwezinto eziphilayo.Isixhobo sesinyithi somhlaba esingaqhelekanga kwi-organic synthesis.I-Lewis acid catalyst ekwazi ukumelana namanzi isandula kusetyenziswa kwimbiza enye ye-β-lactam, kunye ne-stereocontrolled radical and nucleophilic addition reactions.Catalyzes synthesis of deoxypenostatin A kwinoveli, stereoelective, intramolecular Diels-Alder reaction.I-Lewis acid catalyst esetyenziswe kunye ne-silylated chinchona alkaloid kwi-asymmetric synthesis ye-beta-lactam efakwe endaweni ye-acid chloride kunye ne-aryl imine.Ikwasetyenziselwa ukwenza i-aldehyde-ene reaction in the synthesis of guaiane skeleton.I-Lewis acid eyi-catalyst ebalulekileyo yeendlela ezahlukeneyo zokwenziwa kwezinto zokwenziwa, kuquka i-alylborations.
