context_page_description: An azo coupling is an organic reaction between a diazonium compound and another aromatic compound that produces an azo compound. In this electrophilic aromatic substitution reaction, the aryldiazonium cation is the electrophile and the activated arene is a nucleophile. In most cases, including the examples below, the diazonium compound is also aromatic.
context_section_description: In alkaline media, diazonium salt can react with most primary and secondary amines that exist as a free base and produce triazene. This chemical reaction is called azo N-coupling or the synthesis of azoamines.
