Tetrabutylammonium iodide, inozivikanwawo seTBAI, inoshandiswa zvakanyanya mukuita kwakasiyana kwemakemikari.Imwe yeanonyanya kunakidza uye akadzidzwa zvakanyanya mashandisirwo eTBAI iko kushandiswa kwayo mukubatanidzwa kweazides.Asi chii chiri kumashure kwemhinduro iyi, uye TBAI inobatsira sei pairi?
Maitiro ekupindura eTBAI akaomarara uye anosanganisira akati wandei akakosha matanho.Kazhinji, kuita uku kunosanganisira in situ chizvarwa che hypoiodite kubva kuTBAI uye co-reactant inozivikanwa seTBHP.Iyi hypoiodite inobva yasangana nekabhonil compound kuti igadzire yepakati inozopedzisira yanzi azide.Pakupedzisira, hypoiodite inovandudzwa zvakare neoxidation.
Nhanho yekutanga mukuita maitiro inosanganisira chizvarwa che hypoiodite kubva kuTBAI uye TBHP.Iri inhanho yakakosha nekuti inotanga kuita nekupa iyo inodiwa mhando yeiodine kune inotevera carbonyl oxidation.Hypoiodate inoshanda zvakanyanya uye inokwanisa kusimudzira maitiro mazhinji akasiyana emakemikari, kusanganisira halogenation uye oxidation.
Kana hypoiodite yangoumbwa, inopindirana nekomboni yecarbonyl kuumba yepakati.Izvi zvepakati zvinobva zvagadziriswa uchishandisa imide reagent, iyo inowedzera maatomu maviri enitrogen kumorekuru uye "inoimisa" kuti iwedzere kuita.Panguva ino, TBAI yakashanda chinangwa chayo uye haichadiwi mukuita.
Nhanho yekupedzisira mumagetsi inosanganisira kuvandudzwa kwe hypoiodite.Izvi zvinowanikwa neoxidation uchishandisa co-reactants senge hydrogen peroxide.Kudzoreredza iyo hypoiodite kwakakosha nekuti inobvumira maitiro kuti aenderere mberi nekuchovha bhasikoro uye kugadzira mamwe azides.
Pakazere, maitiro eTBAI ekupindura akanakisa uye anoshanda.Nekugadzira hypoiodite in situ uye nekuishandisa kuita oxidize carbonyl makomisheni, TBAI inogonesa kugadzirwa kweazides izvo zvingave zvakaoma kana kusagoneka kubatanidza.Kunyangwe iwe uri kemisitiri anoshanda murabhoritari yekutsvagisa kana mugadziri ari kutsvaga kugadzira zvinyorwa zvitsva, TBAI ine zvakawanda zvekupa.Edza nhasi!
