Abstract
Palladium coordinated in N-heterocyclic carbene-functionalized porous organic polymer ([email protected]) was successfully prepared via a facile copolymerization and successive immobilization method. The obtained [email protected] that featured relatively large surface area, hierarchical pore structure, and strong electron interaction between Pd species and bis-NHC ligand, displayed very high catalytic activity for the oxidative carbonylation of glycerol. A 0.025 mol% of Pd loading was sufficient for 96% conversion of glycerol with a high turnover frequency (TOF) of 1901 h−1. Moreover, the catalyst could be reused at least nine consecutive recycles without obvious loss of its initial activity.
