Ifeza trifluoromethanesulfonate, izwi kandi nka AgOTf, ni reagent ikomeye kandi ihindagurika ikoreshwa muburyo butandukanye bwo guhindura imiti.Ni mubyiciro bya triflates yicyuma, bifite akamaro kanini muri synthesis organique bitewe na acide ya Lewis hamwe nubushobozi bwo gukora substrate.Bimwe mubikorwa byingenzi bya silver trifluoromethanesulfonate ni nkumusemburo mubikorwa bya reaction.Irashobora koroshya impinduka zitandukanye, zirimo karubone-karubone ihuza reaction, nka Friedel-Crafts alkylation na acylation reaction, hamwe na karuboni-azote ikora reaction, nka N-acylation ya amine cyangwa synthesis ya amide.Imiterere ya acide ya Lewis ya AgOTf ituma ishobora guhuza na substrate ikungahaye kuri electron, biganisha kumikorere yimiti yihariye kandi ikorohereza ibyifuzo.Ibikorwa byayo bya catalitiki bifite agaciro cyane cyane muguhuza imiti, imiti y’ubuhinzi, n’imiti myiza.AgOTf nayo ifite akamaro mu guteza imbere gahunda yo guhindura ibintu no kuzunguruka.Irashobora guhagarika uburyo butandukanye bwo guhindura ibintu, nka Beckmann rearrangement, ihindura oximes muri amide cyangwa est est, cyangwa guhinduranya alcool ya allylic kugirango ibe karubone.Ikigeretse kuri ibyo, irashobora gufasha muburyo bwo kuzunguruka, bigafasha gushiraho ibice byuzuzanya hamwe na sisitemu igoye.Imiterere ya acide ya Lewis ya AgOTf igira uruhare runini muribi bitekerezo byorohereza gahunda zingirakamaro zingirakamaro hamwe nintambwe yo kuzunguruka.Ikindi kandi, ifeza trifluoromethanesulfonate ikoreshwa mugukora karuboni-hydrogène (CH).Irashobora gukora imigozi ya CH iherekejwe nitsinda ryimikorere, nko mubikorwa bya aromatic CH bond cyangwa gukora allylic cyangwa benzylic CH.Uku gukora kwemerera gukora nyuma yumurongo wa CH, biganisha kumikorere mishya ya karubone-karubone cyangwa karubone-heteroatom.Ubu buryo, buzwi nka CH activation, ni umurima wihuta cyane muri synthesis organique kandi utanga inzira nziza yo kugera kuri molekile igoye. Birakwiye ko tumenya ko AgOTf yunvikana nubushuhe numwuka, bityo igomba gukemurwa mugihe cyagenwe.Ubusanzwe ikoreshwa muke, nkumubare wa catalitiki, kubera reaction nyinshi.Hagomba kwitonderwa gukorera ahantu hafite umwuka uhagije no kurinda reagent kutagira ubushuhe.Muri make, silver trifluoromethanesulfonate (AgOTf) ni reagent yingirakamaro kandi itanga umusemburo wa synthesis.Kamere ya acide ya Lewis ituma ikora substrate, igateza imbere gahunda yo guhinduranya no guhinduranya ibintu, no gukora imigozi ya CH, bigatuma habaho molekile zikomeye.Ariko rero, hagomba gufatwa ingamba mugihe ukoresha no kubika AgOTf kugirango ihamye kandi ikumire ingaruka zitifuzwa.
