Gomberg-bachmann-hey reaction

WebThe Gomberg-Bachmann reaction is usually conducted in a two- phase system, an aqueous alkaline solution, that also contains the arenediazonium salt, and an organic layer containing the other aromatic reactant. Yields can be improved by use of a phase transfer catalyst. Otherwise yields often are below 40%, due to various side reactions taking ...
