Ntchito:

1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) (CAS: 6674-22-2) ndi bicyclic amidine base.Ndi non-nucleophilic, sterically chotchinga, tertiary amine base mu organic chemistry.Amanenedwa kuti ndi apamwamba kuposa chothandizira cha amine mu Baylis-Hillman reaction.Imalimbikitsa methylation reaction ya phenols, indoles ndi benzimidazoles ndi dimethyl carbonate pansi pazikhalidwe zofatsa.
DBU ikhoza kugwiritsidwa ntchito:
1. DBU ndi amidinebase amphamvu.Kutumikira monga pulotoni mkangaziwisi DBU makamaka ntchito monga sanali nucleophilic maziko mu synthesis ambiri yogwira mankhwala zosakaniza.
2. DBU imagwiritsidwa ntchito mu organic synthesis monga chothandizira, ligand complexing, ndi non-nucleophilic base.Amagwiritsidwa ntchito ngati chitetezo cha kaphatikizidwe ka cephalosporin komanso ngati chothandizira polyurethane.
3. Monga chothandizira carboxylic acid esterification ndi dimethyl carbonate
4. DBU imagwiritsidwa ntchito ngati resin kuchiritsa accelerator (makamaka pachivundikiro chakunja cha mabwalo ophatikizika ndi zida zamagetsi).
5. Monga chothandizira mu aza-Michael Kuwonjezera ndi Knovenegal condensation anachita
6. DBU imagwiritsidwa ntchito ngati chothandizira pamakampani a polyurethane.Ndilo chothandizira kwambiri, chochepa cha fungo la gel.DBU imagwiritsidwa ntchito makamaka pazovuta zomwe ma gels amphamvu amafunikira, kuphatikiza ma ester cycloisocyanates kapena aliphatic isocyanates, omwe amafunikira zopangira zamphamvu chifukwa sagwira ntchito kwambiri kuposa ma isocyanate onunkhira.
7. DBU imagwiritsidwa ntchito popanga heterocycle ndi zofunika zapakati pamankhwala ndi mankhwala ophera tizilombo kapena kaphatikizidwe ka block.
8. Angagwiritsidwe ntchito ngati chothandizira kuvunda ndi kutsegula kwa mapadi ndi reversible anachita ake hydroxyl magulu ndi mpweya woipa.Dongosolo la cellulose losungunukali limatha kuchotsedwa kuti lipange ma esters osakanikirana a cellulose.
9. DBU imagwiritsidwa ntchito popanga mankhwala a cephalosporin semi-synthetic antibiotic, komanso amagwiritsidwa ntchito popanga ma deacidification agents, rust inhibitors, advanced corrosion inhibitors, etc.
