Air stable ligandless heterogeneous catalyst systems based on Pd and Au supported in SiO2 and MCM-41 for Suzuki-Miyaura cross-coupling in aqueous medium

- Pd and Pd-Au based catalysts were prepared by the sol-gel method and MCM-41suports.
- The catalysts were evaluated for Suzuki reaction in air and without ligands.
- The catalysts were evaluated for Suzuki reaction in water as solvent.
- The catalytic behavior could be influenced by the nature of the catalyst employed.
- The Au metal showed influence in the catalytic behavior.
