Tetrabutylammonium iodide, eo hape e tsejoang e le TBAI, ke reagent e sebelisoang haholo liketsong tse fapaneng tsa lik'hemik'hale.E 'ngoe ea likopo tse khahlang le tse ithutoang haholo tsa TBAI ke ts'ebeliso ea eona ha ho etsoa li-azides.Empa ts'ebetso ea karabelo ee ke efe, 'me TBAI e kenya letsoho joang ho eona?
Mokhoa oa karabelo oa TBAI o rarahane haholo mme o kenyelletsa mehato e mengata ea bohlokoa.Ka kakaretso, karabelo ena e kenyelletsa tlhahiso ea in situ ea hypoiodite ho tsoa ho TBAI le se sebetsang-'moho se tsejoang e le TBHP.Hypoiodite ena ebe e sebetsa le motsoako oa carbonyl ho etsa sebaka sa mahareng se ka morao e leng azide.Qetellong, hypoiodite e tsosolosoa hape ka oxidation.
Mohato oa pele oa mokhoa oa ho arabela o kenyelletsa ho hlahisa hypoiodite ho tloha TBAI le TBHP.Ena ke mohato oa bohlokoa hobane e qala karabelo ka ho fana ka mefuta e hlokahalang ea iodine bakeng sa khabonel oxidation e latelang.Hypoiodate e sebetsa haholo 'me e khona ho khothaletsa liphetoho tse ngata tse fapaneng tsa lik'hemik'hale, ho kenyelletsa halogenation le oxidation.
Hang ha hypoiodite e etsoa, e kopana le motsoako oa carbonyl ho theha bohareng.Sebaka sena se bohareng se sebelisoa ho sebelisa sesebelisoa sa imide, se eketsang liathomo tse peli tsa naetrojene ho molek'hule 'me ha e le hantle e "e kenya tšebetsong" bakeng sa likarabelo tse ling.Mothating ona, TBAI e sebelitse morero oa eona mme ha e sa hlokahala karabelong.
Mohato oa ho qetela oa mochine o kenyelletsa ho tsosolosoa ha hypoiodite.Sena se finyelloa ka ho sebelisa li-co-reactants tse kang hydrogen peroxide.Ho tsosolosa hypoiodite ho bohlokoa hobane ho lumella karabelo ho tsoela pele ho palama libaesekele le ho hlahisa li-azide tse ngata.
Ka kakaretso, mokhoa oa karabelo oa TBAI o motle haholo ebile o sebetsa hantle.Ka ho hlahisa hypoiodite in situ le ho e sebelisa ho oxidize metsoako ea carbonyl, TBAI e nolofalletsa ho hlahisa li-azides tseo ho seng joalo ho neng ho tla ba thata kapa ho ke ke ha khoneha ho li kopanya.Hore na o setsebi sa k'hemistri se sebetsang ka laboratoring ea lipatlisiso kapa moetsi ea batlang ho hlahisa lisebelisoa tse ncha, TBAI e na le lintho tse ngata tseo e ka fanang ka tsona.E leke kajeno!
