The Front Cover shows the process of the dehydrogenative coupling of 1‐phenylethanol catalyzed by a Brønsted acid depicted as scissors. The scissors cut off water from the benzylic alcohol to form benzylic carbocations (yellow jigsaw pieces) and vinylarenes (orange jigsaw pieces), which can be attached to each other to form a cationic dimeric species. Further orange jigsaw pieces could now be added quite easily, forming oligomeric species. This is inhibited by the presence of triphenylphosphine (blue jigsaw piece) in catalytic amounts, leading to the desired dimeric alkene. More information can be found in the Communication by I. Fleischer et al.
