Taupānga:

Ko te 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) (CAS: 6674-22-2) he turanga amidine bicyclic.Kore-nucleophilic, he mea aukati, he turanga amine tuatoru i roto i te matū waro.E kiia ana he pai ake i te whakakorikori amine i te tauhohenga Baylis-Hillman. Ka whakatairanga i te tauhohenga methylation o nga phenols, indoles me te benzimidazoles me te dimethyl carbonate i raro i nga tikanga ngawari.
Ka taea te whakamahi i te DBU:
1. Ko te DBU he amidinebase kaha.Ko te mahi hei kaipara iraoho DBU te nuinga o te tono hei turanga kore-nucleophilic i roto i te whakahiatotanga o te maha o nga kai rongoa kaha.
2. Ka whakamahia te DBU i roto i te whakahiato waro hei whakakorikori, he herenga uaua, me te turanga kore-nucleophilic.Ka whakamahia hei maataki tiaki mo te whakahiato o te cephalosporin me te whakakorikori mo te polyurethane.
3. Hei whakakorikori mo te waikawa warowaikawa esterification ki te dimethyl carbonate
4. Ka whakamahia te DBU hei kapia whakaora whakatere (ina koa mo te uhi o waho o nga waahanga hiko me nga waahanga hiko).
5. Hei whakakōkī i te tāpiritanga aza-Michael me te tauhohenga condensation Knovenegal
6. Ka whakamahia te DBU hei whakakorikori i roto i te ahumahi polyurethane.He tino hohe, he iti te kakara o te reera.Ko te DBU te nuinga e whakamahia ana i roto i nga ahuatanga catalytic e hiahiatia ana nga reera kaha, tae atu ki nga hanganga kei roto i nga cycloisocyanates ester, i nga isocyanates aliphatic ranei, e hiahia ana ki te whakakorikori kaha na te mea he iti ake te kaha i te isocyanates kakara.
7. Ka whakamahia te DBU mo te whakahiato o te heterocycle me te takawaenga nui o te rongoa me te pesticide, te whakahiato waro ranei o te poraka.
8. Ka taea te whakamahi hei whakakorikori mo te wetewete me te whakahohe o te cellulose e te tauhohenga whakahuri o ona roopu hydroxyl me te hauhā.Ka taea te hanga i tenei punaha cellulose rewa ki te hanga i nga hākawa whakaurunga cellulose.
9. Ka whakamahia te DBU ki te hanga i nga raau taero antibiotic semi-synthetic cephalosporin, ka whakamahia ano hoki i roto i te whakarite o nga apiha deacidification, te aukati waikura, te aukati waikura matatau, me era atu.
