Tetrabutylammonium iodide, tseem hu ua TBAI, yog ib qho tshuaj reagent siv dav hauv ntau yam tshuaj tiv thaiv.Ib qho kev nthuav dav tshaj plaws thiab kev kawm dav siv ntawm TBAI yog nws siv hauv kev sib txuas ntawm azides.Tab sis dab tsi yog lub tswv yim tom qab cov lus teb no, thiab TBAI pab txhawb rau nws li cas?
Cov txheej txheem teb ntawm TBAI yog qhov nyuaj heev thiab suav nrog ntau cov kauj ruam tseem ceeb.Feem ntau, cov tshuaj tiv thaiv no cuam tshuam txog kev tsim cov tshuaj hypoiodite los ntawm TBAI thiab cov co-reactant hu ua TBHP.Qhov no hypoiodite ces reacts nrog ib tug carbonyl compound los tsim ib tug intermediate uas yog tom qab azide.Thaum kawg, hypoiodite yog regenerated dua los ntawm oxidation.
Thawj kauj ruam nyob rau hauv cov tshuaj tiv thaiv mechanism yog tsim los ntawm hypoiodite los ntawm TBAI thiab TBHP.Qhov no yog ib kauj ruam tseem ceeb vim tias nws pib cov tshuaj tiv thaiv los ntawm kev muab cov tshuaj iodine tsim nyog rau carbonyl oxidation tom ntej.Hypoiodate yog reactive heev thiab muaj peev xwm los txhawb ntau yam tshuaj sib txawv, nrog rau halogenation thiab oxidation.
Thaum hypoiodite yog tsim, nws reacts nrog carbonyl compound los tsim ib qho nruab nrab.Qhov nruab nrab no yog tom qab ntawd azidated siv ib qho imide reagent, uas ntxiv ob lub nitrogen atoms rau lub molecule thiab qhov tseem ceeb "activates" nws rau cov tshuaj tiv thaiv ntxiv.Nyob rau lub sijhawm no, TBAI tau ua haujlwm rau nws lub hom phiaj thiab nws tsis xav tau hauv cov tshuaj tiv thaiv ntxiv lawm.
Cov kauj ruam kawg hauv cov txheej txheem suav nrog kev rov tsim dua ntawm hypoiodite.Qhov no yog ua tiav los ntawm oxidation siv co-reactants xws li hydrogen peroxide.Regenerating lub hypoiodite yog ib qho tseem ceeb heev vim hais tias nws tso cai rau cov tshuaj tiv thaiv mus ntxiv cycling thiab tsim ntau azides.
Zuag qhia tag nrho, TBAI cov lus teb mechanism yog qhov zoo nkauj heev thiab ua haujlwm tau zoo.Los ntawm kev tsim cov hypoiodite nyob rau hauv situ thiab siv nws los oxidize carbonyl tebchaw, TBAI enables tiam ntawm azides uas yuav tsis yooj yim los yog tsis yooj yim sua kom synthesize.Txawm hais tias koj yog ib tus kws kho mob ua haujlwm hauv chav tshawb fawb lossis cov chaw tsim khoom tab tom nrhiav los tsim cov ntaub ntawv tshiab, TBAI muaj ntau yam.Sim nws hnub no!
