Palladium supported on an ion exchange resin for the Suzuki‐Miyaura reaction A B S T R A C T A basic anion exchange resin, Amberlite IRA‐900, was loaded with Pd(C3H5)(C5H5) by an easy metal‐organic chemical vapor deposition (MOCVD) approach to give Pd@IRA‐900 catalyst after reduction at room temperature. Ultraviolet‐Visible spectroscopy results showed a red shift of the absorption peak of Pd2+after the Pd precursor was loaded on the resin, indicating that a chemical reaction occurred between the precursor and the support. Pd nanoparticles with 2.6nm of average size were well dispersed on the support.The Pd@IRA‐900 catalyst showed high activity for different kinds of aryl halides in Suzuki‐Miyaura coupling reactions under mild and aerobic conditions. Excellent recyclability of Pd@IRA‐900 catalyst was also observed in the Suzuki‐Miyaura coupling reaction of iodobenzene and phenylboronic acid.A bifunctional catalyst Pd@IRA‐900(OH) was synthesized by pretreating the ion exchange resin support with NaOH before Pd loading, which successfully catalyzed the Suzuki‐Miyaura reaction of iodobenzene and phenylboronic acid without base under aerobic conditions. |
