Highly active palladium nanoparticles immobilized on knitting microporous organic polymers as efficient catalysts for Suzuki–Miyaura cross-coupling reaction

By encaging the Pd nanoparticles in the interior space of the hypercrosslinked microporous organic polymer, we successfully prepared a novel eco-friendly heterogeneous catalyst for Suzuki cross-coupling reaction. The catalyst afforded fast conversions for the Suzuki cross-coupling reaction even at a loading of 0.05 mmol% Pd, and the turnover frequency for the reaction could be up to 61,353 h−1. Furthermore, this catalyst is stable enough to be reused more than five times with no appreciable activity decrease. This work provides a method for fabricating highly active microporous organic polymer encapsulated Pd catalysts for Suzuki cross-coupling reaction and resolve the problem of industrialization in traditional active carbon catalysts.
