What specialized chemical reaction leverages the extreme reactivity of a diazonium salt to forcefull — Amines Chemistry Question
Question
What specialized chemical reaction leverages the extreme reactivity of a diazonium salt to forcefully couple it directly with an unactivated arene (such as pure liquid benzene) in an alkaline environment to successfully synthesize a biaryl compound like biphenyl?
💡 Solution & Explanation
The Gomberg-Bachmann reaction specifically relies on the base-catalyzed physical decomposition of an aryl diazonium salt in the direct physical presence of another unactivated aromatic liquid (like pure benzene). It undergoes a radical-based mechanism to forcefully cross-couple the rings, yielding a biaryl structure such as biphenyl.
