Isicelo:

I-1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) (i-CAS: 6674-22-2) isisekelo se-bicyclic amidine.Akuyona i-nucleophilic, ivinjiwe, isisekelo se-amine ephakeme ku-organic chemistry.Kubikwa ukuthi iphakeme kune-amine catalyst ku-Baylis-Hillman reaction.Ikhuthaza ukusabela kwe-methylation kwama-phenols, ama-indoles nama-benzimidazoles ane-dimethyl carbonate ngaphansi kwezimo ezithambile.
I-DBU ingasetshenziswa:
1. I-DBU iyi-amidinebase eqinile.Ukukhonza njenge-proton scavenger DBU isetshenziswa kakhulu njengesisekelo esingeyona i-nucleophilic ekuhlanganisweni kwezithako eziningi zemithi esebenzayo.
2. I-DBU isetshenziswa ku-organic synthesis njenge-catalyst, i-ligand eyinkimbinkimbi, kanye nesisekelo esingeyona i-nucleophilic.Isetshenziswa njenge-ejenti evikelayo yokuhlanganiswa kwe-cephalosporin futhi njenge-catalyst ye-polyurethane.
3. Njenge-catalyst ye-carboxylic acid esterification ene-dimethyl carbonate
4. I-DBU isetshenziswa njengesisheshisi sokuphulukisa i-resin (ikakhulukazi isembozo sangaphandle samasekethe ahlanganisiwe kanye nezingxenye ze-elekthronikhi).
5. Njenge-catalyst ekungezeni kwe-aza-Michael kanye ne-Knovenegal condensation reaction
6. I-DBU isetshenziswa njenge-catalyst embonini ye-polyurethane.Kuyinto esebenzayo kakhulu, ijeli catalyst enephunga eliphansi.I-DBU isetshenziswa kakhulu ezimeni ze-catalytic lapho kudingeka khona amajeli aqinile, okuhlanganisa ukwakheka okuqukethe ama-ester cycloisocyanates noma ama-aliphatic isocyanate, adinga ama-catalyst aqinile ngoba awasebenzi kangako kunama-isocyanate anuka kamnandi.
7. I-DBU isetshenziselwa ukuhlanganiswa kwe-heterocycle kanye nokubalulekile okuphakathi kwemithi kanye ne-pesticide noma i-organic synthesis ye-block.
8. Ingasetshenziswa njenge-catalyst yokuhlakazwa kanye nokwenza kusebenze kwe-cellulose ngokusabela okubuyisela emuva kwamaqembu ayo e-hydroxyl ne-carbon dioxide.Lesi simiso se-cellulose esincibilikisiwe singakhishwa ukuze sakhe i-cellulose ester exubile.
9. I-DBU isetshenziswa ekwenziweni kwezidakamizwa ze-cephalosporin semi-synthetic antibiotic, futhi isetshenziswa nasekulungiseleleni ama-agent e-deacidification, ama-rust inhibitors, ama-advanced corrosion inhibitors, njll.
