Inside Back Cover: A Simple Synthesis of Triangular All-Metal Aromatics Allowing Access to Isolobal All-Metal Heteroaromatics (Chem. Eur. J. 35/2015)

The famous dream of the ouroboros, the symbol of the circle, which inspired Kekulè’s structure of benzene leading to the concept of aromatic chemistry, can also be applied to metals. Noble metals can be assembled in molecules with an equilateral metal core. This regular geometry remains untouched even if mixing different atoms, as a result of cyclic electron delocalization, leading to all-metal aromatics and all-metal heteroaromatics. More details can be found in the Communication by G. Maestri et al. on page 12271 ff
