Synthesis of fluorinated biaryl derivatives via SRN1 reactions
Flourinated biaryl derivatives Y-C6-H4-ArOH (Y = F, CF3, OCF3) are obtained by coupling Y-C6-H4-Br(p) with anions derived from ArOH via a photostimulated SRN1 reaction.

SRN1C-arylation of potassium aryloxides by arylazo phenyl or tert- butyl sulfides in DMSO
Aryloxide ions (Ar′O-) behave as C-nucleophiles towards diazosulfides (ArN = NSR; R = Ph, But) 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 SRN1 mechanism is proposed on the grounds of experimental evidences.
