Novel polymer supported iminopyridylphosphine palladium (Ⅱ) complexes: An efficient catalyst for Suzuki–Miyaura and Heck cross-coupling reactions

A novel cross-linked polyallylamine polymer supported iminopyridylphosphine palladiumⅡ complexes have been prepared and shown to be highly efficient catalysts for Suzuki–Miyaura and Heck cross-coupling reactions under low Pd loading (0.05% mol). Remarkably, the catalyst can be recycled and reused without loss of catalytic activity through simple filtration.
