diazonium coupling reaction

Diazonium coupling is a chemical process where a diazonium ion, a positively charged nitrogen compound, reacts with another aromatic compound, like phenol or aniline. This reaction forms a new, larger dye-like molecule called an azo compound, which often has vivid colors. The process involves the diazonium ion attaching itself to the aromatic ring through a substitution reaction. This method is widely used in dye manufacturing and for creating colored compounds in the laboratory, offering a controlled way to introduce color into organic molecules.
