Ytterbium(III) Trifluoromethanesulfonate Hydrate CAS 54761-04-5 Purity >98.0% (Chelometric Titration)

Ytterbium(III) Trifluoromethanesulfonate Hydrate (CAS: 54761-04-5) imagwira ntchito ngati chothandizira mu organic synthesis of heterocycles.Imagwiranso ntchito ngati Lewis acid mumitundu yosiyanasiyana yama organic.Chothandizira chosiyanasiyana cha Rare Earth mu organic synthesis.Chothandizira cha Lewis acid cholekerera madzi chomwe chimagwiritsidwa ntchito posachedwapa mumphika umodzi wopangidwa ndi β-lactam, ndi stereocontrolled radical and nucleophilic add reactions.Imathandizira kaphatikizidwe ka deoxypenostatin A mu buku, stereoselective, intramolecular Diels-Alder reaction.Lewis acid chothandizira chogwiritsidwa ntchito ndi silylated chinchona alkaloid mu asymmetric synthesis wa m'malo β-lactam kuchokera asidi chloride ndi aryl imine.Amagwiritsidwanso ntchito poyambitsa aldehyde-ene reaction mu kaphatikizidwe ka mafupa a guaiane.Chofunika kwambiri cha Lewis acid chothandizira pazinthu zosiyanasiyana zopanga, kuphatikizapo allylborations.
