Binuclear complex of platinum (I) and palladium (I) showed superior activity in Suzuki-Miyaura coupling reaction of aryl halides with arylboronic acids compared to the sole palladium or platinum species. The catalyst showed good tolerance in water and coupling reactions were performed in water as a green solvent. Aryl iodides were reacted at room temperature and the reactions of aryl bromides were performed at 60 °C.
