Abstract

We report on the synthesis, characterization and catalytic performance of new, supported PdII and Pd0 catalysts. The catalysts are characterized by TEM, XRD, FTIR, X-ray photoelectron spectroscopy, and vibrating sample magnetometry. The catalysts are found to be active in both forms, PdII and Pd0, for the carbonylative cross-coupling reaction of aryl iodides with arylboronic acids, and for the hydrogenation of aromatic nitro- and unsaturated compounds. The newly developed catalysts are prepared by a synthetic strategy that is similar to the one used for other supported catalysts but are easier to recover—they can be recycled by magnetic separation from liquid phase reactions—and can be used for at least 5 consecutive trials without any decrease in activity.
