Ibicuruzwa

Litiyumu trifluoromethanesulfonate, izwi kandi nka LiOTf, ni reagent ikomeye kandi itanga umusemburo wa synthesis.Numunyu ukorwa no guhuza lithium cations (Li +) na trifluoromethanesulfonate anion (OTf-).LiOTf ikoreshwa cyane muburyo butandukanye bwimiti bitewe nuburyo bwihariye nubushobozi bwo koroshya impinduka zifuzwa.Bimwe mubikorwa byingenzi bya lithium trifluoromethanesulfonate ni nka catisale ya Lewis.Irashobora gukora amatsinda atandukanye ikora hamwe na substrate, igateza imbere reaction zirimo gushiraho imikoranire mishya.LiOTf ifite akamaro kanini muguhindura imikorere ya karuboni-ogisijeni (CO), nko muri reaction ya acetalisation, aho yorohereza gukora acetale iva kuri alcool.Irashobora kandi gukora izindi bond zirimo heteroatom, nka karubone-azote (CN), ituma habaho amide cyangwa imine.Gukoresha LiOTf nkumusemburo utuma ibintu byoroha byitwara neza, ingufu nke zikenerwa, hamwe no guhitamo neza.LiOTf nayo ikoreshwa nkisoko ya lithium cations mubitekerezo bitandukanye.Litiyumu nicyuma cyingirakamaro ion gishobora kugira uruhare mubitekerezo bitandukanye, nkibisubizo byuma-catisale byambukiranya hamwe nibisubizo bya nucleophilique.LiOTf itanga isoko yoroshye kandi yoroshye kuboneka ya lithium kuri izi mpinduka.Byongeye kandi, anion ya trifluoromethanesulfonate irashobora gukora nka compteur, kuringaniza amafaranga ya lithium cation no guhuza abahuza reaction. Byongeye kandi, LiOTf isanga porogaramu muri chimie synthique kubushobozi bwayo bwo gukemura no guhuza abahuza reaction.Irashobora gukora nkigikorwa cyo guhuza ibishishwa, byoroshya ibisubizo birimo ibyuma byinzibacyuho cyangwa ubundi bwoko bwibinyabuzima.Byongeye kandi, LiOTf ikunze gukoreshwa nka electrolyte muri bateri ya lithium-ion kubera ituze ryayo hamwe n’umuvuduko mwinshi wa ionic. Birakwiye ko tumenya ko LiOTf igomba kwitonderwa bitewe nubushobozi bwayo bushobora gukongoka no gutwikwa.Igomba kubikwa ahantu hakonje, humye, kure yubushyuhe nubushyuhe.Kimwe n'indi myunyu ya lithium, LiOTf itera ibyago byo kwangirika k'ubushyuhe kandi irashobora kubyara imyuka y'ubumara iyo ihuye n'ubushyuhe bwinshi. Muri make, lithium trifluoromethanesulfonate (LiOTf) ni reagent itandukanye kandi itanga umusemburo wa synthesis.Acide ya Lewis, ubushobozi bwo gutanga lithium cations, hamwe na solubilizing ituma bigira agaciro muburyo butandukanye bwo guhindura imiti.Nyamara, gufata neza no kubika neza bigomba gufatwa kugirango bikoreshwe neza.
