P-DCB from DI chloro benzene

Can one take P dichlorobenzene and react it with MeCN to give P Dicyanobenzene.  ??

MeCN won't probably work but alkalimetal cyanides should.

[Pimpo]

Alkali cyanides generally don't convert aryl halides to nitriles, even activated ones. Anhydrous CuCN does react at 200°C. Look at Organic Syntheses, CV 3, 212 (9-CYANOPHENANTHRENE) and Organic Syntheses, CV 3, 631 (a-NAPHTHONITRILE). Note that heavier halogens generally react better.

Is ther a more common name for  Dicyanobenzene

[Rhodium]

1,4-Benzodinitrile perhaps?

[Aurelius]

And why was it misinforming? An explanation would be appreciated.

[Pimpo]

Hey Aurelius, dunno who rated your post   , but the reason is the following: diazonium ions are formed from aromatic AMINES and nitrous acid, not from aromatic HALIDES. Your idea should work, but you'd have to tetrazotize (i.e. diazotize twice) p-phenylenediamine.

I think I need more sleep.  That's two very obvious misses I've made recently.
