Abstract
Recent progress in the chemistry of arenediazonium salts are reviewed and discussed from a viewpoint of their synthetic applications. The reactions described in the article are as follows : a) cyclization reactions in which the diazonium nitrogen is lost or retained ; b) reactions with nucleophiles at the terminal nitrogen ; c) replacements of diazonio group by hydrogen, halogens, hydroxyl, and other groups ; d) arylation reactions which involve Gomberg-Bachmann and Meerwein types of the reaction.
