Lithium trifluoromethanesulfonate, kuma aka sani da LiOTf, wani muhimmin reagent ne kuma mai kara kuzari a cikin hadadden kwayoyin halitta.Gishiri ne da aka samar ta hanyar haɗin lithium cations (Li+) da trifluoromethanesulfonate anions (OTf-).Ana amfani da LiOTf sosai a cikin halayen sinadarai daban-daban saboda ƙayyadaddun kaddarorin sa da ikon sauƙaƙe canje-canjen da ake so.Daya daga cikin mahimman aikace-aikacen lithium trifluoromethanesulfonate shine azaman mai haɓaka acid na Lewis.Yana iya kunna ƙungiyoyin ayyuka daban-daban da maɓalli, suna haɓaka halayen da suka haɗa da samuwar sabbin shaidu.LiOTf yana da matukar tasiri a cikin kunna kunnawar carbon-oxygen (CO), kamar a cikin amsawar acetalization, inda yake sauƙaƙe samuwar acetals daga barasa.Hakanan yana iya kunna sauran haɗin haɗin heteroatom, kamar abubuwan haɗin carbon-nitrogen (CN), yana ba da damar samuwar amides ko imines.Amfani da LiOTf a matsayin mai kara kuzari yana ba da damar yanayi mai sauƙi, ƙarancin buƙatun makamashi, da ingantaccen zaɓi.Lithium ion ƙarfe ne mai amfani wanda zai iya shiga cikin kewayon halayen, kamar halayen haɗin giciye-karfe da halayen maye gurbin nucleophilic.LiOTf yana ba da dacewa da samuwa tushen lithium don waɗannan canje-canje.Bugu da ƙari, trifluoromethanesulfonate anion na iya zama abin juzu'i, daidaita cajin cation na lithium da daidaita matsakaicin amsawa.Bugu da ƙari, LiOTf yana samun aikace-aikace a cikin sinadarai na roba don ikonsa na solubilize da daidaita matsakaicin amsawa.Yana iya aiki azaman mai daidaita ƙarfi, sauƙaƙe halayen da suka haɗa da abubuwan haɓaka ƙarfe na miƙa mulki ko wasu nau'ikan amsawa.Bugu da ƙari kuma, ana amfani da LiOTf sau da yawa azaman electrolyte a cikin batura lithium-ion saboda kwanciyar hankali da haɓakar ionic.Ya kamata a adana shi a wuri mai sanyi, busasshiyar wuri, nesa da danshi da tushen zafi.Kamar sauran gishirin lithium, LiOTf yana haifar da haɗari na bazuwar thermal kuma yana iya haifar da hayaki mai guba lokacin da aka fallasa shi zuwa yanayin zafi.Lewis acidity ɗin sa, ikon samar da cations na lithium, da kaddarorin masu narkewa suna sa ya zama mai daraja ga sauye-sauyen sinadarai iri-iri.Koyaya, ya kamata a ɗauki matakan kulawa da kyau don tabbatar da amincin amfani da shi.
