Mechanochemical in Situ Encapsulation of Palladium in Covalent Organic Frameworks

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(36), P. 13535 - 13543

Palladium-encapsulated covalent organic frameworks (Pd/COFs) have garnered enormous attention in heterogeneous catalysis. However, the dominant ex situ encapsulation synthesis is tedious (multistep), time-consuming (typically 4 days or more), and involves use of noxious solvents. Here we develop a mechanochemical strategy that enables one-step, time-efficient, environmentally benign Pd/COFs. By ball milling COF precursors along with palladium acetate (Pd(OAc)2) one pot under air at room temperature, Pd/COF hybrids were readily synthesized within an hour, exhibiting high crystallinity, uniform Pd dispersion, superb scalability up to gram scale. Moreover, this versatile can be extended three Remarkably, resulting Pd/DMTP-TPB showcases extraordinary activity (96–99% yield 1 h temperature) broad substrate scope (>10 functionalized biaryls) for Suzuki–Miyaura coupling reaction aryl bromides arylboronic acids. Furthermore, heterogeneity verified by recycling leaching tests. The disclosed herein paves facile, rapid, scalable, avenue access metal/COF catalysts efficient
