Abstract

Abstract An ultrafast and highly efficient ligand-free Suzuki–Miyaura cross-coupling reaction between aryl bromides/iodides and arylboronic acids using palladium chloride as catalyst in PEG400/H 2 O in air at room temperature has been developed. TEM showed that palladium nanoparticles were generated in situ from PdCl 2/PEG400/H 2 O without use of other reductants. The catalyst system can be recycled to reuse three times with good yields.
