The Front Cover shows the skyline of Mainz illuminated by a sunset. Above the skyline, iodine, illustrated as a flying hero masked with an oxygen bandage, absorbs the sunlight and is now able to attack the thioglycoside. A combination of molecular iodine with oxygen enables the catalytic activation of thioglycosides upon irradiation with visible light. After cleavage of the C–S‐bond, the glycosyl cation and phenyl disulfide are released. The former then reacts with an alcohol yielding O ‐glycosides. Oxygen serves as the terminal oxidant for the reaction and regenerates the iodine catalyst. Graphic designed by L. Großmann (Mainz) and graphic elements licensed by Shutterstock.
