1,8-Diazabicyclo[5,4,0]undec-7-ene CAS:6674-22-2

1,8-Diazabicyclo[5,4,0]undec-7-ene (DBU) e sebelisoa haholo lits'ebetsong tse ngata, haholo-holo ts'ebetsong ea tlhaho le lik'hemik'hale. E le motheo o sebetsang hantle oa non-nucleophilic, e sebelisoa ho ntšeng protonation ea metsoako ea asiti, joalo ka alcohols le carboxylic acids, ho nolofatsa liphetoho tse fapaneng tsa maiketsetso. DBU e boetse e sebetsa e le sesosa sa liketso tsa polymerization, e nolofalletsang tlhahiso ea li-polymer tse khethehileng le li-resin. Ho feta moo, e sebelisoa ho kopanyeng metsoako ea meriana le metsoako e sebetsang, e bapala karolo ea bohlokoa ho sibolloeng le nts'etsopele ea lithethefatsi. Bokhoni ba eona ba ho khothaletsa liketso tsa condensation le cyclization bo atolosa thuso ea eona ho theheng limolek'hule tse rarahaneng tsa tlhaho. Ho feta moo, DBU e sebelisoa haholo lefapheng la mahlale a thepa bakeng sa ho lokisa thepa e sebetsang le lik'hemik'hale tse ikhethang tse nang le lits'ebetso tse fapaneng ho lipente, likhomaretsi le lisebelisoa tsa elektroniki. Ho feta moo, ts'ebeliso ea eona ho kopanyeng ha asymmetric le liketso tse entsoeng ka tšepe e totobatsa bohlokoa ba eona ho hlahiseng metsoako ea chiral le lik'hemik'hale tse ntle. Ka kakaretso, mefuta e mengata ea lits'ebetso tsa 1,8-Diazabicyclo[5,4,0]undec-7-ene e totobatsa bohlokoa ba eona ho ntšetseng pele ts'ebetso ea ho kopanya lik'hemik'hale le ea indasteri.
