Mawu Oyamba

1,8-Diazabicyclo [5.4.0] undec-7-ene, yomwe imadziwika kuti DBU, ndi yofunika kwambiri.

Chilengedwe:

1. Maonekedwe ndi Maonekedwe: Ndi madzi opanda mtundu komanso owoneka bwino. Lili ndi fungo lamphamvu la ammonia komanso mayamwidwe amphamvu a chinyezi.

2. Kusungunuka: Kusungunuka muzinthu zambiri zosungunulira za organic, monga ethanol, etha, chloroform, ndi dimethylformamide.

3. Kukhazikika: Ndizokhazikika ndipo zimatha kusungidwa kwa nthawi yayitali kutentha kwapakati.

4. Kuyaka: Kukhoza kuyaka ndipo kuyenera kupewedwa kuti zisakhumane ndi magwero a moto.

Kagwiritsidwe:

1. Catalyst: Ndi maziko amphamvu omwe amagwiritsidwa ntchito ngati chothandizira cha alkaline mu kaphatikizidwe ka organic, makamaka mu kaphatikizidwe ka condensation, m'malo, ndi ma cyclization.

2. Wosinthana ndi ion: amatha kupanga mchere wokhala ndi ma organic acid ndikugwira ntchito ngati anion exchange agent, yomwe imagwiritsidwa ntchito popanga organic synthesis ndi analytical chemistry.

3. Chemical reagents: amagwiritsidwa ntchito mu hydrogenation zimachitikira, deprotection zimachitikira, ndi amine m'malo zimachitikira catalyzed ndi zapansi amphamvu mu kaphatikizidwe organic.

Njira:

Itha kupezeka pochita 2-Dehydropiperidine ndi ammonia. Njira yeniyeni ya kaphatikizidwe ndizovuta ndipo nthawi zambiri imafunikira labotale yopangira organic kuti igwire.

Zambiri zachitetezo:

1. Imakhala ndi dzimbiri ndipo imatha kuyambitsa kuyabwa pakhungu ndi maso. Mukamagwiritsa ntchito, magolovesi oteteza ndi magalasi ayenera kuvala kuti musagwirizane.

2. Posunga ndi kugwiritsa ntchito ma DBUs, malo olowera mpweya wabwino ayenera kusamalidwa kuti achepetse kuchuluka kwa fungo ndi nthunzi.

3. Pewani kuchitapo kanthu ndi ma okosijeni, zidulo, ndi zinthu zakuthupi, ndipo pewani kugwira ntchito pafupi ndi kumene kuli moto.

4. Pogwira zinyalala, chonde tsatirani malamulo amderalo ndi njira zoyendetsera chitetezo.

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