Hey mate this is your answer ❤️❤️❤️
Synthesis of Aryl Halides
The two most common methods of preparing aryl halides are by direct halogenation of benzene and via diazonium salt reactions.
Halogenation of benzene
The halogenation of benzene to synthesize aryl halides is the oldest method known.
I hope it helps you ❤️❤️❤️
Have a great day ❤️❤️❤️❤️

Sandmeyer reaction
A second method for preparing aryl halides is the Sandmeyer reaction. During a Sandmeyer reaction, a diazonium salt reacts with copper (I) bromide, copper (I) chloride, or potassium iodide to form the respective aryl halide. The diazonium salt is prepared from aniline by reaction with nitrous acid at cold temperatures.
