ʻO 1,8-Diazabicyclo [5.4.0] undec-7-ene (DBU) (CAS: 6674-22-2) kahi kumu amidine bicyclic.ʻAʻole ia he nucleophilic, ʻaʻole i hoʻopaʻa ʻia, kumu amine tertiary i loko o ke kemika organik.Ua hōʻike ʻia ʻoi aku ka maikaʻi ma mua o ka amine catalyst ma Baylis-Hillman reaction. Hoʻolaha ia i ka hopena methylation o nā phenols, indoles a me benzimidazoles me ka dimethyl carbonate ma lalo o nā kūlana haʻahaʻa.
Hiki ke hoʻohana ʻia ka DBU:
1. ʻO DBU kahi amidinebase ikaika.Hoʻohana nui ʻia ka lawelawe ʻana ma ke ʻano he proton scavenger DBU ma ke ʻano he kumu non-nucleophilic i ka synthesis o nā mea lāʻau lapaʻau ikaika.
2. Hoʻohana ʻia ʻo DBU i ka synthesis organik ma ke ʻano he catalyst, kahi ligand paʻakikī, a me kahi kumu non-nucleophilic.Hoʻohana ʻia ia ma ke ʻano he mea pale no ka synthesis o cephalosporin a ma ke ʻano he catalyst no ka polyurethane.
3. E like me ka mea hoʻoikaika no ka esterification waika carboxylic me ka dimethyl carbonate
4. Hoʻohana ʻia ʻo DBU ma ke ʻano he resin curing accelerator (ʻoi loa no ka uhi waho o nā kaapuni i hoʻohui ʻia a me nā ʻāpana uila).
5. E like me ka catalyst i ka aza-Michael hoʻohui a me Knovenegal condensation pane
6. Hoʻohana ʻia ʻo DBU ma ke ʻano he catalyst i ka ʻoihana polyurethane.He mea hoʻoikaika ikaika, haʻahaʻa-ʻala gel catalyst.Hoʻohana nui ʻia ʻo DBU i nā kūlana catalytic kahi e koi ʻia ai nā gels ikaika, me nā formulations i loaʻa i ka ester cycloisocyanates a i ʻole aliphatic isocyanates, e koi ana i nā catalysts ikaika no ka mea ʻoi aku ka liʻiliʻi ma mua o nā isocyanates aromatic.
7. Hoʻohana ʻia ʻo DBU no ka synthesis o heterocycle a me ka waena koʻikoʻi o ka lāʻau lapaʻau a me ka pesticide a i ʻole ka synthesis organik o ka poloka.
8. Hiki ke ho'ohana 'ia ma ke 'ano he mea ho'oikaika no ka ho'ohehe'e 'ana a me ka ho'oulu 'ana o ka cellulose e ka ho'ololi 'ana o kona mau pū'ulu hydroxyl me ka carbon dioxide.Hiki ke hoʻoheheʻe ʻia kēia ʻōnaehana cellulose e hana i nā esters hui pū.
9. Hoʻohana ʻia ʻo DBU i ka hana ʻana i nā lāʻau antibiotic semi-synthetic cephalosporin, a hoʻohana ʻia hoʻi i ka hoʻomākaukau ʻana i nā mea deacidification, nā mea hoʻopiʻi rust, nā mea hoʻopiʻi corrosion kiʻekiʻe, etc.
