Imikhiqizo

I-2,8-Diazabicyclo[4.3.0]nonane, evame ukubizwa ngokuthi i-DBN, iyinhlanganisela yamakhemikhali enesakhiwo esiyingqayizivele esinikeza ukusetshenziswa okubanzi emikhakheni ehlukahlukene.Ku-organic synthesis, i-DBN ivamise ukusetshenziswa njengesisekelo esiqinile se-organic. kanye ne-catalyst.Isakhiwo sayo se-bicyclic sinikeza ukuzinza, siyivumela ukuthi isetshenziswe ekuphenduleni okuhlukahlukene.I-DBN iwusizo ikakhulukazi ekuguqulweni kwezinto eziphilayo lapho kudingeka khona isisekelo esiqinile, njengokuncishiswa kwezinhlanganisela ze-asidi noma ukwakhiwa kwamabhondi e-carbon-nitrogen.Ingase futhi isetshenziswe ekuhlanganiseni kwemithi, amakhemikhali e-agrochemicals, namanye ama-organic molecule ayinkimbinkimbi.I-DBN iphinde isetshenziswe njengesengezo kukhemikhali ye-polymer.Imvelo yayo eyisisekelo ivumela ukuthi isebenze njenge-ejenti engathathi hlangothi ekukhiqizeni amagwebu e-polyurethane nama-elastomers.Isiza ukulawula i-kinetics yokusabela futhi ithuthukise izici ezibonakalayo ze-polymer ewumphumela, njengamandla emishini nokumelana nokushisa.Ukwengeza, i-DBN ingaqashwa njenge-ejenti elaphayo yama-epoxy resins, okuneqhaza ekuxhumaniseni kwawo okuphambanayo kanye nezinqubo ze-polymerization.Ngaphezu kwalokho, i-DBN ithola izinhlelo zokusebenza ezihlukahlukene emkhakheni wezokwelapha.Ingasetshenziswa njengengxenye esebenzayo ekuhlanganisweni kwezidakamizwa, ikakhulukazi ekulungiseleleni izinhlanganisela ze-heterocyclic.Isisekelo salo sivumela ukwakheka kwama-intermediate abalulekile noma ukuguqulwa kwama-molecule ezidakamizwa ukuze kuthuthukiswe umsebenzi wabo wezokwelapha noma izakhiwo.I-DBN futhi isebenza njenge-catalyst ekuphenduleni okuthile kwemithi, njengokuvinjelwa okukhethiwe kwamaqembu okuvikela noma ukwakhiwa kwamabhondi e-peptide.I-DBN ibonise ukuthi iyisisusa esisebenzayo nesiguquguqukayo ku-asymmetric organic synthesis futhi.Ukwakheka kwayo okuyingqayizivele kanye nokuyisisekelo kuyenza ikwazi ukugqugquzela ukusabela okuhlukahlukene kwe-enantioselective, yenze kube lula ukudalwa kwama-molecule e-chiral ane-stereoselectivity ephezulu nokusebenza kahle.Lokhu kuyenza ibe ithuluzi elibalulekile lokuhlanganiswa kwemithi kanye nezinye izinhlanganisela eziphilayo eziyinkimbinkimbi lapho ubuciko bubalulekile khona.Isisekelo sayo esiqinile, ukuzinza, kanye nesakhiwo se-bicyclic esiyingqayizivele siyenza ibe ithuluzi eliguquguqukayo lokusabela okuhlukahlukene kanye nezinhlelo zokusebenza.Kusukela ekusetshenzisweni kwayo njenge-catalyst kanye nesisekelo kukhemistri ephilayo kuya endimeni yayo yokwengeza ezinqubweni ze-polymerization kanye nokusetshenziswa kwayo ekuhlanganiseni kwemithi, i-DBN inikeza amathuba anhlobonhlobo ososayensi nabacwaningi emikhakheni eminingi.
