Recyclable, Bifunctional Metallaphotocatalysts for C?S Cross?Coupling Reactions

Metallaphotocatalytic cross-coupling reactions are typically carried out by combining homogeneous or heterogeneous photocatalysts with a soluble nickel complex. Previous attempts to realize recyclable catalytic systems use immobilized iridium complexes harvest light. We present bifunctional materials based on semiconductors for metallaphotocatalytic C?S that can be reused without losing their activity. Key the success is permanent immobilization of complex surface semiconductor through phosphonic acid anchors. The optimized catalyst harvests broad range visible light spectrum and requires loading only ?0.1 mol %.
