Immobilized palladium nanoparticles on silica–starch substrate (PNP–SSS): As a stable and efficient heterogeneous catalyst for synthesis of p-teraryls using Suzuki reaction
摘要:
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.
