Isicelo:

I-4-Dimethylaminopyridine (i-DMAP) (i-CAS: i-1122-58-3) yinto entsha esebenzayo esebenzayo esetyenziswa ngokubanzi kwi-chemical synthesis.Inomthamo ophezulu we-catalytic kwi-organic synthesis, i-chiza synthesis, i-pesticide, idayi, i-fragrance synthesis ye-acylation, i-alkylation, i-etherification kunye nezinye iintlobo zokuphendula, kwaye inempembelelo ecacileyo kakhulu ekuphuculeni isivuno.Acylation yotywala;i-acylation ye-phenols;I-acylation ye-amines;I-acylation ye-enalates;Iimpendulo ze-isocyanates;ii-Aplikeshini eziNgezinye;Ukudluliselwa kwamaQela aSebenzayo.
I-DMAP, yi-super nucleophilic acylation catalyst.I-resonance yeqela le-electron-donating dimethylamino kwisakhiwo sayo kunye nendandatho yomzali (i-pyridine ring) ingenza ngamandla i-athomu ye-nitrogen kwindandatho yokungena endaweni ye-nucleophilic, eyenza kakhulu ukuchasana okuphezulu, i-alcohols ephantsi-reactive kunye ne-amines / acids Umsebenzi. ye-acylation/esterification reaction imalunga ne-104 ~ 106 amaxesha e-pyridine.Ukutshintshwa kwe-Acyl kukuguqulwa okuqhelekileyo kwindalo kunye ne-organic synthesis, apho i-chiral DMAP yinto eqhelekileyo yokudlulisa i-acyl catalyst.Ukususela ngo-1996, iVedejs kunye neqela le-Fu banike ingxelo ye-chiral ephakathi kunye ne-planar chiral DMAP catalysts ngokulandelanayo, i-chiral DMAP catalysts ziphuhliswe kakhulu.Iintlobo ezahlukeneyo ze-chiral ephakathi, i-planar chiral, i-spiro chiral kunye ne-central chiral DMAP ziye zaxelwa enye emva kwenye, kwaye zisetyenziswe kakuhle kwiimpendulo ezininzi zokudluliselwa kwe-asymmetric acyl.
I-DMAP yi-nucleophilic catalyst eguquguqukayo kakhulu ye-acylation reactions kunye ne-esterifications.Ikwasetyenziswa kwiinguqu ezahlukeneyo zezinto eziphilayo ezifana ne-Baylis-Hillman reaction, i-Dakin-West reaction, ukukhuselwa kwe-amines, i-C-acylations, i-silylations, izicelo kwi-chemistry yeemveliso zendalo, kunye nabanye abaninzi.
I-DMAP ingasetyenziselwa njenge-catalyst: Kuba i-acylation ye-alcohol kunye ne-anhydrides ye-asidi phantsi kwe-axiliary base- kunye neemeko ezingenayo i-solvent-free ukudibanisa i-esters ehambelanayo.Kwi-Baylis-Hillman reaction to form carbon-carbon bond ngokudibanisa i-alkene esebenzayo kunye ne-aldehyde okanye i-ketone.
I-catalyst esebenzayo kakhulu ye-acylation reactions.
