Tetrabutylammonium iodide, yomwe imadziwikanso kuti TBAI, ndi reagent yomwe imagwiritsidwa ntchito kwambiri pamachitidwe osiyanasiyana amankhwala.Chimodzi mwazinthu zosangalatsa komanso zophunziridwa kwambiri za TBAI ndikugwiritsa ntchito kwake popanga azides.Koma ndi njira yotani yomwe imathandizira kuyankha uku, ndipo TBAI imathandizira bwanji?
Njira yoyankhira ya TBAI ndiyovuta kwambiri ndipo imaphatikizapo njira zingapo zofunika.Nthawi zambiri, izi zimaphatikizapo in situ generation ya hypoiodite kuchokera ku TBAI ndi co-reactant yotchedwa TBHP.Hypoiodite iyi imakhudzidwa ndi kaphatikizidwe ka carbonyl kupanga chapakati chomwe pambuyo pake chimakhala azide.Pomaliza, hypoiodite imapangidwanso ndi okosijeni.
Gawo loyamba pamakina amachitidwe limaphatikizapo kubadwa kwa hypoiodite kuchokera ku TBAI ndi TBHP.Ichi ndi sitepe yofunika kwambiri chifukwa imayamba kuchitapo kanthu popereka mitundu yofunikira ya ayodini kuti ichitike pambuyo pa carbonyl oxidation.Hypoiodate imagwira ntchito kwambiri ndipo imatha kulimbikitsa machitidwe osiyanasiyana amankhwala, kuphatikiza ma halogenation ndi okosijeni.
Hypoiodite ikapangidwa, imakhudzidwa ndi kaphatikizidwe ka carbonyl kupanga wapakatikati.Izi zapakatikati zimasinthidwa pogwiritsa ntchito imide reagent, yomwe imawonjezera maatomu awiri a nayitrogeni ku molekyuluyo ndipo makamaka "amayambitsa" kuti achitenso zina.Pakadali pano, TBAI yakwaniritsa cholinga chake ndipo sikufunikanso pakuchitapo kanthu.
Gawo lomaliza pamakina limaphatikizapo kusinthika kwa hypoiodite.Izi zimatheka ndi okosijeni pogwiritsa ntchito co-reactants monga hydrogen peroxide.Kubwezeretsanso hypoiodite ndikofunikira chifukwa kumapangitsa kuti zomwe zikuchitika zipitilize kuyendetsa njinga ndikupanga azides ambiri.
Ponseponse, njira yoyankhira ya TBAI ndiyabwino kwambiri komanso yothandiza.Popanga hypoiodite in situ ndikugwiritsa ntchito oxidize carbonyl compounds, TBAI imathandizira kupanga azides zomwe zingakhale zovuta kapena zosatheka kupanga.Kaya ndinu katswiri wa zamankhwala yemwe amagwira ntchito mu labotale yofufuzira kapena wopanga yemwe akufuna kupanga zinthu zatsopano, TBAI ili ndi zambiri zoti ipereke.Yesani lero!
