Azides preparation from diazonium ions

Aryl substrates containing suitable leaving and activating groups react readily with moderately strong nucleophiles such as azide ion and a number of aromatic azides have been prepared in this manner (Table 4). Such Ar reactions complement the synthesis of aromatic azides from diazonium compounds zind are of particular value in forming azides of heteroaromatic systems in which dizizotization procedures are unsatisfactory,...
