Henkel reaction

What is Henkel reaction?

The Henkel reaction, which is also referred to as the Raecke process, is an industrial-scale chemical transformation involving the thermal rearrangement or disproportionation of alkaline salts derived from aromatic acids. This process occurs in the presence of metallic salts, such as cadmium, and results in the formation of symmetrical diacids.
