Article abstract of DOI:10.1016/S0040-4020(01)90095-X

Aryloxide ions (Ar′O^-) behave as C-nucleophiles towards diazosulfides (ArN = NSR; R = Ph, Bu^t) leading to imsymmetrical hydroxybiaryls (ArAr′OH) via C-C coupling. The reaction is particularly suited for the synthesis of terms which contain electron-withdrawing groups on the Ar moiety. The S_RN1 mechanism is proposed on the grounds of experimental evidences.
