A recyclable and non‐phosphine solid palladium (II) catalyst was prepared and characterized by HR‐MS , FT‐IR , XPS , EDS , TGA , SEM , TEM and ICP . The Pd‐catalyst exhibited high‐performance catalytic activity in Suzuki and Heck C‐C coupling reactions in an environmentally benign water medium. Further, the Pd‐catalyst ( Z 4 ) can be reused for 15 times with little decrease of activity through simple and efficient recovery. In addition, the turn‐over number (TON) of Pd‐ catalyst can reach 380 at room temperature. These results proved that the Pd‐catalyst has a stable structure and can be recycled many times, making the process sustainable.
