Lithium trifluoromethanesulfonate, e taʻua foi o le LiOTf, o se mea taua tele ma faʻamalosi i le faʻaogaina o meaola.O se masima e faia i le tuufaatasiga o lithium cations (Li +) ma trifluoromethanesulfonate anion (OTf-).O le LiOTf e faʻaaogaina lautele i vailaʻau faʻamaʻi eseese ona o ona uiga faʻapitoa ma le gafatia e faʻafaigofie ai suiga manaʻomia.O se tasi o faʻaoga autu o le lithium trifluoromethanesulfonate o le Lewis acid catalyst.E mafai ona fa'agaoioia vaega fa'atino eseese ma substrates, fa'alauiloa tali e aofia ai le fa'avaeina o fusi fou.LiOTf e sili ona aoga i le faʻamalosia o le faʻagaoioia o fusi carbon-oxygen (CO), e pei o le acetalization reaction, lea e faʻafaigofie ai le faʻavaeina o acetals mai ava malosi.E mafai foʻi ona faʻagaoioia isi faʻamauga o loʻo i ai le heteroatom, e pei o le carbon-nitrogen (CN) bonds, e mafai ai ona faʻavaeina amides poʻo imines.O le faʻaogaina o le LiOTf e fai ma faʻamalosi e mafai ai ona faʻamalieina tulaga faʻafefe, maualalo manaʻoga malosi, ma faʻaleleia le filifilia. LiOTf e faʻaaogaina foi e fai ma puna o lithium cation i gaioiga eseese.Lithium ose u'amea aoga e mafai ona auai i le tele o tali, e pei o le uamea-catalyzed cross-coupling reactions ma nucleophilic substitution reactions.O le LiOTf e maua ai se puna o le lithium e faigofie ma faigofie mo nei suiga.E le gata i lea, o le trifluoromethanesulfonate anion e mafai ona avea ma se faʻataʻitaʻiga, faapaleniina o le tau o le lithium cation ma faʻamautu faʻalavelave faʻalavelave.E mafai ona galue e pei o se solvent fa'amaopoopo, fa'afaigofie gaioiga e aofia ai fa'aupuga u'amea fa'aliliu po'o isi ituaiga fa'afoliga.E le gata i lea, o le LiOTf e masani ona faʻaaogaina e avea o se eletise i maa lithium-ion ona o lona mautu ma le maualuga o le faʻaogaina o le ionic. E taua le matauina o le LiOTf e tatau ona taulimaina ma le faʻaeteete ona o lona faʻaogaina ma le mu.E tatau ona teuina i se nofoaga malulu, matutu, mamao ese mai le susu ma le vevela.E pei o isi masima lithium, o le LiOTf o loʻo i ai se lamatiaga o le faʻaleagaina o le vevela ma e mafai ona maua ai asu oona pe a faʻaalia i le maualuga o le vevela.O lona Lewis acidity, gafatia e tuʻuina atu lithium cations, ma solubilizing meatotino e taua tele mo suiga eseese o vailaʻau.Ae ui i lea, e tatau ona faia ni puipuiga lelei o le taulimaina ma le teuina ina ia mautinoa lona faʻaogaina saogalemu.
