Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

this reaction is called von richter reaction..... when halo-nitrobenzene is reacted with KCN at 420 C..... the nitro group leaves and the cyano group occupies the position ortho to nitro group....... so the product is 1-cyano-2-bromo-benzene .... here is the named reaction..... von Richter Reaction.
