P-DCB from DI chloro benzene | Bookmark | ||||||
Can one take P dichlorobenzene and react it with MeCN to give P Dicyanobenzene. ?? Start thinking more like a chemist and less like a criminal |

MeCN won't probably work but alkalimetal ... | Bookmark | ||||||
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. |

Is ther a more common name for Dicyanobenzene Start thinking more like a chemist and less like a criminal |

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

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. Act quickly or not at all. |
