Isicelo:

I-4-Dimethylaminopyridine (DMAP) (i-CAS: i-1122-58-3) i-catalyst entsha esebenza kahle kakhulu esetshenziswa kabanzi ekuhlanganiseni kwamakhemikhali.Inamandla amakhulu e-catalytic ku-organic synthesis, synthesis yezidakamizwa, isibulala-zinambuzane, udayi, iphunga elimnandi le-acylation, i-alkylation, i-etherification nezinye izinhlobo zokusabela, futhi inomphumela osobala kakhulu ekuthuthukiseni isivuno.I-acylation yotshwala;i-acylation ye-phenols;I-acylation yama-amine;i-acylation ye-enolates;Ukusabela kwe-isocyanates;Izinhlobonhlobo Zokusebenza;Ukudluliselwa Kwamaqembu Asebenzayo.
I-DMAP, i-super nucleophilic acylation catalyst.I-resonance yeqembu le-electron-donating dimethylamino esakhiweni salo kanye nendandatho engumzali (indandatho ye-pyridine) ingenza kusebenze i-athomu ye-nitrogen eringini ukuze ingene esikhundleni se-nucleophilic, evuselela kakhulu ukumelana notshwala obuphansi kanye nama-amine/ama-acids Umsebenzi. ukusabela kwe-acylation/esterification cishe izikhathi eziyi-104 ~ 106 kune-pyridine.Ukudluliswa kwe-Acyl kuwuguquko oluvamile emvelweni kanye nokuhlanganiswa kwezinto eziphilayo, lapho i-chiral DMAP iyisisusa esivamile sokudlulisa i-acyl.Kusukela ngo-1996, i-Vedejs nethimba le-Fu babike ukuthi ama-catalyst e-DMAP e-chiral aphakathi nendawo kanye ne-planar chiral ngokulandelana, ama-chiral DMAP catalysts athuthukiswe kakhulu.Izinhlobonhlobo ze-central chiral, i-planar chiral, i-spiro chiral kanye ne-central chiral DMAP kuye kwabikwa ngokulandelana, futhi kusetshenziswe kahle ekuphenduleni okuningi kokudluliswa kwe-asymmetric acyl.
I-DMAP iyi-nucleophilic catalyst eguquguquka kakhulu yokusabela kwe-acylation kanye ne-esterifications.Iphinde isetshenziswe ekuguquleni okuhlukahlukene kwezinto eziphilayo njenge-Baylis-Hillman reaction, ukusabela kwe-Dakin-West, ukuvikelwa kwama-amines, ama-C-acylations, ama-silylations, ukusetshenziswa kumakhemikhali wemikhiqizo yemvelo, nokunye okuningi.
I-DMAP ingasetshenziswa njenge-catalyst: Ukuze kuhlanganiswe ama-alcohol ane-acid anhydrides ngaphansi kwezimo ezisizayo nezingenayo i-solvent ukuze kuhlanganiswe ama-ester ahambisanayo.Ekuphenduleni kwe-Baylis-Hillman ukwakha ibhondi ye-carbon-carbon ngokuhlangana kwe-alkene ecushiwe ne-aldehyde noma i-ketone.
I-catalyst esebenza kahle kakhulu yokusabela kwe-acylation.
