Abstract
Supported Pd nanoparticles on acetyl acetone modified silica gel was prepared and its catalytic application in the Suzuki–Miyaura reaction of various aryl halides with phenylboronic acid was investigated. The reaction was carried out in water as solvent under green conditions in the presence of NaHCO3as the base. The catalyst was characterized by a combination of powder XRD, XPS, TEM and SEM. The catalyst is not sensitive to air and moisture, so reactions were carried out without using inert atmosphere. The catalyst can be reused up to six times without significant loss of catalyst activity. The cumulative turnover number (TON) over six runs is 13525.
