Isingeniso

I-1,8-Diazabicyclo [5.4.0] undec-7-ene, eyaziwa ngokuthi i-DBU, iyinhlanganisela ebalulekile yezinto eziphilayo.

Imvelo:

1. Ukubukeka Nokubukeka: Iwuketshezi olungenambala futhi olusobala. Inephunga elinamandla le-ammonia kanye nokumunca umswakama oqinile.

2. Ukunyibilika: Kuncibilika kuzincibilikisi eziningi ezivamile, njenge-ethanol, i-ether, i-chloroform, ne-dimethylformamide.

3. Ukuzinza: Izinzile futhi ingagcinwa isikhathi eside ekamelweni lokushisa.

4. Ukuvutha: Kuyavutha futhi kufanele kugwenywe ukuthintana nemithombo yomlilo.

Ukusetshenziswa:

1. I-Catalyst: Iyisisekelo esiqinile esivame ukusetshenziswa njenge-alkaline catalyst ku-organic synthesis, ikakhulukazi ekuphenduleni kwe-condensation, ukusabela kokushintshanisa, nokusabela kokuhamba ngamabhayisikili.

2. I-ejenti yokushintshanisa i-ion: ingakha usawoti ngama-asidi aphilayo futhi isebenze njenge-ejenti yokushintshanisa i-anion, evame ukusetshenziswa ku-organic synthesis kanye namakhemikhali okuhlaziya.

3. Ama-Chemical reagents: avame ukusetshenziswa ekuphenduleni kwe-hydrogenation, ukusabela kokuvikela, kanye nokusabela esikhundleni se-amine okubangelwa izisekelo eziqinile ku-organic synthesis.

Indlela:

Ingatholakala ngokusabela i-2-Dehydropiperidine nge-ammonia. Indlela ethile yokuhlanganisa inzima futhi ngokuvamile idinga ilabhorethri ye-organic synthesis ukuze yenziwe.

Ulwazi lokuphepha:

1. Inokugqwala okuqinile futhi ingase ibangele ukucasuka esikhumbeni nasemehlweni. Uma usebenzisa, amagilavu okuvikela kanye nezibuko kufanele kugqokwe ukugwema ukuthintana okuqondile.

2. Lapho ugcina futhi usebenzisa ama-DBU, indawo enomoya omuhle kufanele igcinwe ukuze kuncishiswe ukugcwala kwephunga nezihwamuko.

3. Gwema ukusabela ngama-oxidants, ama-asidi, nezinhlanganisela eziphilayo, futhi ugweme ukusebenza eduze nemithombo yomlilo.

4. Lapho uphatha udoti, sicela uhambisane nemithetho yendawo kanye nezinqubo zokusebenza zokuphepha.

Okwedlule: 5-[[(2-Aminoethyl) thio]methyl]-N N-dimethyl-2-furfurylamine (CAS# 66356-53-4)

Olandelayo: 2-(2 2-difluorobenzo[d][1 3]dioxol-5-yl)acetonitrile (CAS# 68119-31-3)
