Merrifield’s Resin-Supported Palladium–Bis(oxazoline) Complex-Catalyzed Cross-Coupling Reactions of Aryl Bromides and Aryl Chlorides

Abstract

The catalytic activity and the recycling ability of palladium–bis(oxazoline) (Pd–BOX-M) complex supported on Merrifield’s resin have been investigated in Suzuki–Miyaura and Mizoroki–Heck cross-coupling reactions of aryl bromides and aryl chlorides. The supported palladium–bis(oxazoline) catalyst demonstrated exceptional catalytic activity and excellent recycling ability. The characterization of the recycled palladium catalyst reveals no significant change in its structure, oxidation state and the amount of loaded palladium. This confirms the excellent stability of the palladium-supported catalyst.
