synthetic uses of aryl diazonium salts

Aryl diazonium salts are prepared by reacting an aromatic primary amine with nitrous acid at a temperature between 0-5 oC. Diazonium salts are very useful intermediates in the synthesis of a number of aromatic compounds. Some of them are as follows. 1. Replacement of Hydrogen: Synthesis of 1,3,5,-tribromobenzene 2. Replacement by halogen atom:     Synthesis … Read more
