Article abstract of DOI:10.1016/S0040-4020(01)88316-2

Dichloroaluminium phenolates 4 undergo highly selective FeCl₃-promoted oxidative coupling. Variously substituted symmetric 2,2′-dihydroxy biaryls 2 are obtained in good yields and excellent selectivities. The chelation control in the final reaction products 7 promotes the chemoselectivity of the process.
