This cover picture mainly focuses on the Copper‐catalyzed reaction between carbodiimides and diaryliodonium salts by cleavage of four C(sp3)−H, one C−N, and one C=N bonds. The core creativity is to demonstrate the various interesting bond functionalizations. All these functionalities are located around the Cu catalyst, and the edge of the flask marks all the broken bonds; the backbone fragments in the flask can be selectively combined and form the final products. The Cu‐catalyst “flask” selectively cuts chemical bonds and pours only the 2‐aminopryimidine products. More information can be found in the Communication by W.‐X. Zhang, Z. Xi et al. on page 757 ff.
