Preparation and reactions of diazonium salts. II. Reactions of ArN2+

Abstract

Arenediazonium slats can react with nucleophiles in three ways: (1) The substitution of diazonium group by nucleophile, (2) the substitution of a substituent at ortho or para position by a nucleophile, (3) the addition of a nucleophile to the diazonium group producing the corresponding diazo compound Ar-N=N-Nu od a five- or six-membered ring if the nucleophile is presented by an ortho-standing substituent with regard to the diazonium group.
