The cover feature shows how the high antiaromaticity of the planar cyclooctatetraene core in a dithieno[3,4‐ b :3’,4’‐ d ]thiophene cyclic dimer is retained during one‐electron and peracid oxidation reactions. Inspired by a counterclockwise base‐run in baseball, the picture shows how the “run” in this study was the formation of the sulfoxide species that has a negative relative hardness and a paratropic ring current (typically shown in a counterclockwise direction). Details are given in the Full Paper by T. Nishinaga and co‐workers on page 704 in Issue 6, 2019 (DOI: 10.1002/cplu.201900064).
