High surface hybrid silica materials containing di(2-pyridyl)methylamine–palladiumdichloridecomplex covalently bonded to the silica matrix were prepared by sol-gel process and successfully tested as reusable catalysts for Suzuki cross-coupling reactions.

di-(2-pyridyl)methylamine-palladium dichloride complex, prepared by sol-gel cogelification, are efficient recyclable catalysts for Suzuki (aryl bromides and chlorides), Heck (aryl bromides) and Sonogashirareactions (aryl iodides and bromides). Formation of palladium(0) nanoparticles is observed in the Suzuki and Heckreactions but not in the Sonogashira coupling.
