Suzuki-Miyaura reactions in PEG-water solutions using Pd/BaSO4 as catalytic source

Suzuki-Miyaura reactions between halobenzenes and other substituted (hetero)arenes and boronic acids were carried out in PEG-water solution using Pd/BaSO4 as catalytic source in a ligand-free system. High to moderate yields were generally obtained. The catalytic system could be recycled up to six times, showing a slight decrease in activity after each cycle.
