This paper reports the Donnan exclusion driven intermatrix synthesis (DEDIMS) of Pd polymer-stabilized metal nanocatalysts (PSMNCs) in an anion exchange resin as a novel heterogeneous catalyst for Suzuki cross-coupling reaction (SCCR). An average diameter of the obtained PSMNCs was around 35 nm and the catalytic performance was found to be proportional to the Pd content in the nanocomposite. Stability of the catalyst was evaluated within several reaction cycles. (c) 2012 Elsevier B.V. All rights reserved.
