Polymer‐supported palladium (II) containing N₂O₂: An efficient and robust heterogeneous catalyst for C–C coupling reactions

Abstract

A new polymer was prepared from 1,3,5‐triformylphloroglucinol (noted as TDTB) and o‐phenylenediamine through Schiff base condensation reaction, and palladium (II) was immobilized on the polymer (noted as TbPo‐Pd(II)). This process was easy to work‐up and cost‐effective. The structure and composition of TbPo‐Pd(II) were fully characterized by FTIR, TGA, XPS, AAS, SEM, and TEM analyses. Meanwhile, this catalyst showed desired thermal stability and excellent performance in water/methanol system for Suzuki and Sonogashira coupling reactions. In addition, this heterogeneous catalyst can be readily recovered by simple filtration with no appreciable Pd leaching in the reaction. This work provides a powerful protocol for rapid access to asymmetrical biphenyls and aryl alkynes. © 2018 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2018, 56, 2344–2353

Self‐Generation of Surface Roughness by Low‐Surface‐Energy Alkyl Chains for Highly Stable Superhydrophobic/Superoleophilic MOFs with Multiple Functionalities

“…Many catalytic reactions take place under harsh conditions, including in water, acid, and alkali media, and demand organic solvents and heating, so the development of green catalysts that operate in water under mild conditions is important and useful. The successful strategy for the synthesis of the above stable and hydrophobic mixed‐ligand UiO‐67‐Oct‐L 1 ‐X% MOFs paves the way for the construction of hydrophobic MOF catalysts by replacing L 1 with L 2 , which is then available for metalation to introduce catalytic sites.…”

Superhydrophobic MOF/polymer composite with hierarchical porosity for boosting catalytic performance in an humid environment

“…Many MOFs-based catalysts are prone to collapse after prolonged exposure to harsh reaction conditions, including in humid environments, demanding organic solvents, acid and alkali media. 21 Therefore, developing green MOFs-based catalysts that operate in a humid environment under mild conditions is critical and imminent. The successful strategy for the preparation of the above superhydrophobic and stable ZIF-8/PDVB-vim composite paves the way for the construction of superhydrophobic MOF-based catalysts by confining MOF nanocrystals into superhydrophobic porous polymers.…”
