Lithium trifluoromethanesulfonate, oo sidoo kale loo yaqaan LiOTf, waa reagent muhiim ah iyo kicinta isku-dhafka organic.Waa milix ay samaysay isku-darka lithium cations (Li+) iyo trifluoromethanesulfonate anions (OTf-).LiOTf waxaa si weyn loogu isticmaalaa fal-celin kiimikaad oo kala duwan iyadoo ay ugu wacan tahay sifooyinkeeda gaarka ah iyo awoodda ay ku fududeeyaan isbeddellada la rabo.Mid ka mid ah codsiyada muhiimka ah ee lithium trifluoromethanesulfonate waa kicinta aashitada Lewis.Waxay kicin kartaa kooxo kala duwan oo shaqeynaya iyo substrates, kor u qaadida falcelinta ku lug leh samaynta curaarta cusub.LiOTf aad bay waxtar ugu leedahay kicinta kicinta curaarta carbon-oxygen (CO), sida falcelinta acetalization, halkaas oo ay fududayso samaynta acetals ee alkolada.Waxa kale oo ay dhaqaajin kartaa curaarta kale ee heteroatom-ka kooban, sida curaarta carbon-nitrogen (CN), taas oo awood u siinaysa samaynta amides ama imines.Isticmaalka LiOTf sida kicinta ayaa u oggolaanaysa xaaladaha falcelinta khafiifka ah, shuruudaha tamarta hoose, iyo xulashada xulashada oo la wanaajiyey.Lithium waa bir bir ah oo faa'iido leh oo ka qaybqaadan karta falcelinno kala duwan, sida falcelinta isku-xiran ee birta-catalyzed iyo falcelinta beddelka nucleophilic.LiOTf waxay siisaa il ku habboon oo diyaarsan oo lithium ah oo loogu talagalay isbeddelladan.Intaa waxaa dheer, trifluoromethanesulfonate anion waxay u adeegi kartaa sidii ka hortag, isu dheelitirka kharashka lithium cation iyo xasilinta dhexdhexaadiyeyaasha falceliska ah. Intaa waxaa dheer, LiOTf waxay ka heshaa codsiyada kimistariga synthetic ee awoodda ay u leedahay in ay milicsato oo dejiso dhexdhexaadiyeyaasha falcelinta.Waxay u dhaqmi kartaa sidii dareere isku xidha, fududaynta falcelinta ku lug leh kicinta biraha kala guurka ama noocyada kale ee falcelinta.Intaa waxaa dheer, LiOTf waxaa inta badan loo isticmaalaa sida elektrolyte ah ee baytariyada lithium-ion sababtoo ah degenaanshihiisa iyo dhaqdhaqaaqa ionic sare.Waa in lagu kaydiyaa meel qabow oo qalalan, kana fog qoyaanka iyo meelaha kulaylka.Sida milixda kale ee lithium, LiOTf waxa ay keentaa khatar ah in kulaylku xumaado oo waxa ay soo saari kartaa qiiq sun ah marka uu gaadho heer kulka sareAysiidhkeeda Lewis, kartida ay ku bixiso lithium cations, iyo guryaha milmida ayaa ka dhigaya mid qiimo leh oo isbeddello kiimiko ah oo kala duwan ah.Si kastaba ha ahaatee, ka taxadarida saxda ah iyo kaydinta waa in la qaadaa si loo hubiyo isticmaalkeeda badbaadada leh.
