Vismut (III) triflorometansülfonat (CAS: 88189-03-1) bir qator katalitik reaktsiyalarda foydali bo'lgan kuchli Lyuis kislotasidir.Organik uchun katalizatorsintezlar.Vismut (III) triflorometansülfonat Fridel-Krafts asilatsiyasi va allen-enol efirlarining sikloizomerizatsiyasida katalizator vazifasini bajaradi.U o'zini to'g'ridan-to'g'ri almashtirish katalizatori sifatida tutadi va alilik, propargil va benzil spirtlarini sulfanilamidlar, karboksamidlar va karbamatlar bilan almashtirishda ishtirok etadi.Bundan tashqari, u Mukaiyama aldol reaktsiyalarida ham qo'llaniladi.Vismut (III) triflorometansülfonat quyidagi jarayonlarda katalizator sifatida ishlatilishi mumkin: asetallarning himoyasini yo'qotish;tiofen va furanlarning 2-tert-butoksi hosilalarini parchalash;atsetallarning allyatsiyasi natijasida gomoalil efirlarini hosil qiladi.
