Isingeniso

3-nitro-2-cyanopyridine.

 

Ikhwalithi:

I-3-nitro-2-cyanopyridine iyikristalu eqinile engenambala, engancibiliki emanzini ekamelweni lokushisa, encibilika kuzincibilikisi zemvelo ezifana ne-ethanol, i-ether ne-acetone. Inephunga elimnandi elinamandla.

 

Sebenzisa:

I-3-Nitro-2-cyanopyridine ivame ukusetshenziswa njenge-reagent yamakhemikhali ye-cyanoation kanye ne-electrophilic nitrification ekuphenduleni kwe-organic synthesis. Ingasetshenziswa futhi njengendawo ephakathi kodayi kanye nezingulube zokwenziwa kodayi bemvelo.

 

Indlela:

I-3-Nitro-2-cyanopyridine ingalungiswa nge-nitrosylation kanye ne-cyanoation reactions ye-benzene. I-Benzene ingasabela nge-nitric acid ukuze ithole izinhlanganisela ze-phenyl nitro, eziguqulwa zibe yi-3-nitro-2-cyanopyridine nge-cyanoation ngaphansi kwezimo ze-alkaline.

 

Ulwazi Lokuphepha:

I-3-Nitro-2-cyanopyridine iyacasula futhi iyavutha. Amagilavu ​​okuvikela amakhemikhali, izibuko, nezihlangu zobuso kufanele kugqokwe ukuze kuqinisekiswe indawo yaselabhorethri enomoya omuhle.
