Diazonium salt of aromatic amines
WebThe diazonium salts or diazonium compounds are the class of organic compounds with general formula R−N 2+ X −. Here, X is an organic or inorganic anion (for example, Cl –, Br –, BF 4–, etc.) and R is an alkyl or aryl group. The term is derived from two words. ‘ di’ refers to ‘two’, azo is indicative of ‘ nitrogen ’ and ium ...
