The gold(I)‐mediated domino reaction to fused phosphonium fluorenes has been developed. The key achievement in this study was the elucidation of the reaction mechanism, revealing a phosphinoauration and 6‐ endo‐dig cyclization cascade. The cover picture displays the found reaction pathway in an unconventional pool game. In a comfortable atmosphere, the player shoots the golden billiard ball to the phosphadiine, which undergoes phosphinoauration to the phosphindolium species. In a subsequent gold‐exchange event, the 6‐ endo‐dig cyclization takes place, yielding the gold‐phosphafluorene complex. More information can be found in the Full Paper by Y. Vaynzof, A. S. K. Hashmi, et al. on page 7882.
