The cover picture shows an X‐ray illustration of the multidentate ferrocenylpolyphosphane 1,1′,2,2′‐tetrakis(diphenylphosphanyl)‐4,4′‐di‐ tert ‐butylferrocene. The cisoid conformation of the molecule, evidenced at the solid state, is conserved in solution; the phosphorus arrangement led to a rarely demonstrated multiple‐coordination behaviour towards palladium, possibly useful in ultra‐low catalyst loading reactions due to an improved stabilization of the metal atom. The multiple phosphane arms and their orientation resemble the elegant and intelligent creature that is the Giant Pacific Octopus (specimen from the Alaska SeaLife Centre in Seward, photo published with the kind permission of Mollie Tubbs and Jason Wettstein). The catalytic performance in palladium cross‐coupling at ultra‐low catalyst loading is presented in the Microreview by J.‐C. Hierso et al. on page 3767 ff.
