Palladium's disappearing (and reappearing) act within a specially designed reactor that heats only a small area of Pd foil during a Suzuki–Miyaura coupling is described by C. M. Crudden et al. in their Communication on page 3279 ff. Dissolution of Pd occurs only in the heated zone (left SEM image), and only in the presence of aryl iodide, whereas deposition of Pd occurs preferentially on the unheated zones adjacent to the reactive zone (right SEM image).
