      P-DCB from DI chloro benzene  Bookmark   

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

MeCN won't probably work but alkalimetal cyanides should.

For those about to synth,we salute you

      maybe try CuCN  Bookmark   

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.

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

Hey Aurelius, dunno who rated your post wink, 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.

Act quickly or not at all.
