Aryloxide ions (Ar'O-) behave as C-nucleophiles towards diazosulfides (ArN=NSR; R = Ph, But) leading to unsymmetrical 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 SRN1 mechanism is proposed on the grounds of experimental evidences.
芳氧基离子(Ar'O - )表现为向diazosulfides C-亲核试剂(ARN = NSR; R = PH,卜吨),导致不对称hydroxybiaryls(ArAr'OH)通过CC耦合。该反应特别适合于在Ar部分上包含吸电子基团的项的合成。S RN 1机制是根据实验证据提出的。
