Ytterbium (III) triflorometansülfonat gidrat (CAS: 54761-04-5) heterosikllarning organik sintezida katalizator sifatida ishlaydi.Shuningdek, turli xil organik reaksiyalarda Lyuis kislotasi vazifasini bajaradi.Organik sintezda ko'p qirrali noyob tuproqli metal katalizatori.Suvga chidamli Lyuis kislotasi katalizatori yaqinda b-laktamlarning bir qozonli sintezida hamda stereoboshqariladigan radikal va nukleofil qo'shilish reaksiyalarida qo'llanilgan.Yangi, stereoselektiv, molekulyar Diels-Alder reaktsiyasida deoksipenostatin A sintezini katalizlaydi.Lyuis kislota katalizatori silillangan chinchona alkaloidi bilan kislota xlorid va aril imindan almashtirilgan b-laktamlarning assimetrik sintezida ishlatiladi.Shuningdek, guaian skeletining sintezida aldegid-en reaktsiyasini katalizlash uchun ishlatiladi.Turli xil sintetik reaktsiyalar, shu jumladan allilboratsiyalar uchun muhim Lyuis kislotasi katalizatori.
