Front Cover: Intermediates in Friedel‐Crafts Acylation of Fumaryl Halides (Eur. J. Inorg. Chem. 29/2022)

The Front Cover shows the monoacyl cation, which was formed from the reaction of fumaryl fluoride with the Lewis acid SbF5 in SO2ClF solutions. A little man, symbolizing SbF5, is taking away one fluoride ion from the monoacyl cation. A second little man, representing another SbF5, is approaching the remaining acyl fluoride group and wants to take the fluoride ion. However, the ion of the second fluoride, with formation of the diacyl cation, is not possible (based on charge‐charge repulsion). This is why a stop sign is placed in front of the acyl fluoride group. The trivial name of fumaryl fluoride originates from the plant fumaria officinalis, which is displayed in the background. We gratefully acknowledge the Botanische Staatssammlung München, in particular Siegfried Springer, for providing the picture of fumaria officinalis.
