In this study, a new cross-linked chitosan derivative was synthesized by using 2,2'-pyridil as a cross-linking agent. 2,2'-Pyridil cross-linked chitosan was used to as a support material for palladium catalyst. Chitosan-pyridil-based Pd(II) catalyst was tested in the microwave-assisted synthesis of biaryls via Suzuki coupling reactions. The catalyst yielded remarkable TONs of up to 20,000 and TOFs of up to 240,964 by using very low catalyst loading (5 x 10(-3)% mol) in a short reaction time (5 min). The catalyst also showed a better recyclability. (C) 2016 Elsevier B.V.
