A nano tetraimine Pd(0) complex catalyst was successfully used as an efficient heterogeneous catalyst for the phosphine-free palladium-catalysed Suzuki coupling reaction in water at 80 degrees C. This nano tetraimine Pd(0) complex was also used for copper-free Sonogashira reaction in dimethylformamide at 100 degrees C. The catalyst was easily recovered from the reaction mixture by centrifugation and reused for at least six cycles without any significant loss in its catalytic activity. Analysis of the reaction mixture using inductively coupled plasma analysis showed that leaching of palladium from the catalyst was negligible. The reactions can be performed efficiently for aryl iodides, bromides and also chlorides.
