bipyridine‐based covalent organic polymer (COP) was successfully synthesized by condensation of trimesoyl chloride (TMC) and 2,2′‐bipyridine‐5,5′‐diamine (Bpy) under ambient conditions. This material was modified by coordination of PdCl2 to COP framework, affording a hybrid material, Pd@TMC‐Bpy COP, which was applied as a highly efficient heterogeneous catalyst for Suzuki‐Miyaura reaction under ligand‐free conditions

Immobilized palladium nanoparticles on silica-starch substrate (PNP-SSS) were found to be an efficient reusable catalyst for excellent synthesis of teraryls using Suzuki reaction. The catalytic reactivity of PNP-SSS was examined over a set of substrates, demonstrating that it is reactive toward a variety of functionalities. In this process, the PNP-SSS catalyst can be reused more than six times with almost consistent efficiency and can be recovered by simple filtration. (C) 2012 Elsevier B. V. All rights reserved.
