phosphine (POL‐Ph3P) with high phosphorus content has been prepared. The phosphorus‐containing polymer forms a monodentate‐P‐ligated palladium complex, which shows excellent activity in Suzuki–Miyaura cross‐coupling reactions of aryl chlorides. Importantly, the catalyst Pd/POL‐Ph3P is highly stable and can be reused for at least 10 times without losing reactivity.
