PALLADIUM COMPLEXES SUPPORTED ON HYBRID ORGANIC-INORGANIC ZIRCONIUM PHOSPHITE : SELECTIVITY IN THE HECK REACTION

Abstract Supported palladium complex on zirconium phosphite-phosphonate was made from triphenylphosphine phosphonic acid. The supported catalyst showed significant selectivity in the competitive Heck reaction between iodobenzene and different iodobenzoates. The reaction seems to take place between the lamellar of the catalyst.
