I-Ytterbium(III) Trifluoromethanesulfonate Hydrate (CAS: 54761-04-5) isebenza njenge-catalyst ku-organic synthesis yama-heterocycles.Isebenza futhi njenge-Lewis acid ezinhlobonhlobo zokusabela kwe-organic.I-catalyst yensimbi yomhlaba engajwayelekile ehlukahlukene ku-organic synthesis.I-Lewis acid catalyst ekwazi ukumelana namanzi esanda kusetshenziswa ekuhlanganiseni kwebhodwe elilodwa lama-β-lactam, kanye nokusabela kokwengezwa kwe-radical ne-nucleophilic okulawulwa stereocontrolled.Icubungula ukuhlanganiswa kwe-deoxypenostatin A kunoveli, i-stereoselective, i-intramolecular Diels-Alder reaction.I-Lewis acid catalyst esetshenziswa ne-silylated chinchona alkaloid ku-asymmetric synthesis yama-β-lactam afakwe esikhundleni asuka ku-acid chloride ne-aryl imine.Futhi isetshenziselwa ukwenza ukusabela kwe-aldehyde-ene ekuhlanganisweni kohlaka lwamathambo e-guaiane.I-Lewis acid catalyst ebalulekile yokusabela okuhlukahlukene kokwenziwa, okuhlanganisa ama-alylborations.
