Isicelo:

I-1,8-Diazabicyclo [5.4.0] undec-7-ene (DBU) (i-CAS: 6674-22-2) isiseko se-bicyclic amidine.Ayiyo-nucleophilic, ithintelwe ngokungqongqo, isiseko se-amine senqanaba eliphezulu kwi-organic chemistry.Kubikwa ukuba iphezulu kune-amine catalyst kwi-Baylis-Hillman reaction.Ikhuthaza ukuphendulwa kwe-methylation ye-phenols, i-indoles kunye ne-benzimidazoles kunye ne-dimethyl carbonate phantsi kweemeko ezithambileyo.
I-DBU ingasetyenziswa:
1. I-DBU yi-amidinebase eyomeleleyo.Ukukhonza njengeproton scavenger DBU isetyenziswa ikakhulu njengesiseko esingeyo-nucleophilic ekudibaneni kwezithako ezininzi ezisebenzayo zamayeza.
2. I-DBU isetyenziswe kwi-organic synthesis njenge-catalyst, i-ligand eyinkimbinkimbi, kunye ne-non-nucleophilic base.Isetyenziswe njenge-agent ekhuselayo kwi-synthesis ye-cephalosporin kunye ne-catalyst ye-polyurethane.
3. Njenge-catalyst ye-carboxylic acid esterification kunye ne-dimethyl carbonate
4. I-DBU isetyenziswa njenge-resin curing accelerator (ingakumbi kwi-cover yangaphandle yeesekethe ezidibeneyo kunye namacandelo e-elektroniki).
5. Njenge-catalyst kwi-aza-Michael Ukongeza kunye ne-Knovenegal condensation reaction
6. I-DBU isetyenziswa njenge-catalyst kwishishini le-polyurethane.Yijeli esebenza kakhulu, enevumba eliphantsi.I-DBU isetyenziswa ikakhulu kwiimeko apho kufuneka iijeli ezomeleleyo, kubandakanywa imixube equlathe i-ester cycloisocyanates okanye i-aliphatic isocyanates, efuna ii-catalysts ezinamandla kuba zingasebenzi kancinci kune-isocyanates enuka kamnandi.
7. I-DBU isetyenziselwa ukuhlanganiswa kwe-heterocycle kunye ne-intermediate ebalulekileyo yeyeza kunye ne-pesticide okanye i-organic synthesis yebhloko.
8. Ingasetyenziswa njenge-catalyst yokuchithwa kunye nokusebenza kwe-cellulose ngokuphendula okuguquguqukayo kwamaqela ayo e-hydroxyl kunye ne-carbon dioxide.Le nkqubo ye-cellulose enyibilikisiweyo inokukhutshwa ukuze yenze i-cellulose e-esters edibeneyo.
9. I-DBU isetyenziselwa ukwenza i-cephalosporin semi-synthetic antibiotic drug, kwaye iphinda isetyenziswe ekulungiseleleni i-agent deacidification, i-rust inhibitors, i-advanced corrosion inhibitors, njl.
