Recyclable Porous Organic Polymer-Supported Single-Atom Ruthenium Catalyst for Strong Si–F Bond Activation: Catalytic Si–F/Si–H and Si–F/Si–O Cross-Coupling Reactions

Developing efficient methods for strong Si-F σ-bond activation is very important in organosilicon chemistry. We report the preparation of a novel porous organic polymer (POP)-supported single-atom Ru catalyst (POPs-Ru SACs) that was successfully applied in catalytic strong Si-F/Si-H and Si-F/Si-O cross-coupling reactions. Various disiloxanes with functional group tolerance were produced under mild conditions. Furthermore, the POPs-Ru SACs catalyst exhibited excellent recyclability for Si-F and Si-H cross-coupling reactions. Density functional theory calculations were performed to verify the mechanism of POPs-Ru SACs-catalyzed Si-F/Si-H cross-coupling reactions.
