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

Abstract

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.
