Photoredox-catalyzed cascade difluoromethylation/SO 2 reintegration/polyfluoroarylation of conjugated dienes with a bifunctional CF 2 HSO 2 Na reagent

Key Points

• The cascade reaction enhances difluoromethylation and polyfluoroarylation using visible light.
• Key outcomes involve a bifunctional reagent, CF2 HSO2 Na, in enhancing reaction efficiency.
• The method facilitates SO2 reintegration in conjugated diene contexts, advancing synthetic capabilities.
• Further development could streamline synthesis in materials science and pharmaceuticals, indicating broad applicability.
