Fast X-ray Photoelectron Spectroscopy of Pd-Catalysed Cross-Coupling Surface Reactions Dr Adam F. Lee Background Pd-catalysed cross-coupling reactions are key technologies employed within academia and industry to construct complex molecules from simple precursors. Here we explore alternative, heterogeneous synthetic processes through fundamental single-crystal studies into Heck and Suzuki-Miyaura chemistry over Pd model catalyst surfaces.
