The cover image illustrates a card game based on phosphorus and boron. The Joker card is the title compound 1‐phospha‐7‐bora‐norbornadiene. This card is wild and its behavior depends on the compound card it is played on. For nitriles, an insertion of the C≡N triple bond into the P−B bond is observed, while alkynes undergo a facile 1,4‐addition of the C≡C triple bond with concomitant P−B bond cleavage. The divergent reactivity of the title compound resembles that of a frustrated Lewis pairs (FLP). More information can be found in the Full Paper by R. M. Gschwind, C. Müller, J. C. Slootweg, R. Wolf, et al. on page 7788.
