abstract
Novel heterogeneous silica supported 1,2-bis(ethylthio)ethane palladium and 1,2-bis(ethylthio)propane palladium catalysts are reported. Applied to Suzuki coupling chemistry these catalysts are very effective, reusable and resist leaching at room temperature in isopropanol or in hot xylene. 2007 Elsevier B.V. All rights reserved.
