| Abstract: | We conceptualized a radical cyclization approach for the synthesis of SCF3, SAr, SO2Ar and COAr featured spirocyclic [4.5] and [5.5] trienone between biaryls and ArSO2H or ArCOCO2H in presence of RFTA as a photocatalyst whereas the insertion of ArSSAr or AgSCF3 devoid of photocatalyst via an energetically demanding dearomative transformation under visible-light catalysis. The photo-excited charge transfer complex with biaryl tethered ynones provides a way to promote S-centered radical generation followed by its insertion to enable a wide range of biologically important molecules. © 2024 Wiley-VCH GmbH. |
