The cover picture shows the preparation of 1‐oxoniaadamantane by several different pathways under superacidic conditions. The structure of the intriguing bridgehead oxonium ion was characterized by NMR spectroscopy, DFT calculations and X‐ray crystallography as a CB 11 Cl 16 H 6 counteranion salt. The cation is a missing member of the diamondoid 1‐heteroadamantane series. Details are discussed in the Short Communication by G. K. S. Prakash, G. A. Olah et al. on p. 4555 ff.
