Lithium trifluoromethanesulfonate, yomwe imadziwikanso kuti LiOTf, ndiyofunikira komanso chothandizira pakuphatikizika kwachilengedwe.Ndi mchere wopangidwa ndi kuphatikiza kwa lithiamu cations (Li +) ndi trifluoromethanesulfonate anions (OTf-).LiOTf imagwiritsidwa ntchito kwambiri pamachitidwe osiyanasiyana amankhwala chifukwa cha mawonekedwe ake apadera komanso kuthekera kothandizira kusintha komwe kumafunikira. Chimodzi mwazinthu zazikulu za lithiamu trifluoromethanesulfonate ndi monga chothandizira cha Lewis.Ikhoza kuyambitsa magulu osiyanasiyana ogwira ntchito ndi magawo, kulimbikitsa machitidwe omwe amaphatikizapo kupanga mapangidwe atsopano.LiOTf ndiyothandiza kwambiri pakuyambitsa ma bond a carbon-oxygen (CO), monga momwe amachitira acetalization, pomwe amathandizira kupanga ma acetals kuchokera ku mowa.Itha kuyambitsanso ma bond ena okhala ndi heteroatom, monga ma bondi a carbon-nitrogen (CN), kuthandizira kupanga ma amide kapena imines.Kugwiritsiridwa ntchito kwa LiOTf monga chothandizira kumapangitsa kuti pakhale zovuta zomwe zimachitika, kuchepetsa mphamvu zamagetsi, komanso kusintha kwa kusankha.Lithium ndi ayoni wachitsulo wothandiza omwe amatha kutenga nawo mbali pamachitidwe osiyanasiyana, monga zitsulo zophatikizika zolumikizana ndi ma nucleophilic substitution reaction.LiOTf imapereka gwero losavuta komanso lopezeka la lithiamu pazosinthazi.Kuonjezera apo, trifluoromethanesulfonate anion ikhoza kukhala yotsutsana, kugwirizanitsa mtengo wa lithiamu cation ndi kukhazikika kwapakati.Itha kukhala ngati chosungunulira cholumikizira, chothandizira machitidwe okhudzana ndi zopangira zitsulo kapena mitundu ina yotakasuka.Kuphatikiza apo, LiOTf imagwiritsidwa ntchito nthawi zambiri ngati electrolyte mu mabatire a lithiamu-ion chifukwa cha kukhazikika kwake komanso kupangika kwa ayoni kwambiri.Ndikoyenera kudziwa kuti LiOTf iyenera kusamaliridwa mosamala chifukwa cha kuthekera kwake kuchitanso zinthu komanso kuyaka.Iyenera kusungidwa pamalo ozizira, owuma, kutali ndi chinyezi ndi kutentha.Monga mchere wina wa lifiyamu, LiOTf imapangitsa kuti pakhale chiwopsezo cha kuwonongeka kwa kutentha ndipo imatha kutulutsa utsi wapoizoni ikakumana ndi kutentha kwambiri.Mwachidule, lithiamu trifluoromethanesulfonate (LiOTf) ndi reagent yosunthika komanso chothandizira mu kaphatikizidwe ka organic.Ma acidity ake a Lewis, kuthekera kopereka ma lithiamu cations, ndi zinthu zosungunulira zimapangitsa kuti zikhale zofunikira pakusintha kwamitundu yosiyanasiyana.Komabe, kusamala koyenera ndi kusungirako kuyenera kuchitidwa kuti zitsimikizire kuti zikugwiritsidwa ntchito motetezeka.
