Front Cover Picture: peri‐Xanthenoxanthene (PXX): a Versatile Organic Photocatalyst in Organic Synthesis (Adv. Synth. Catal. 20/2021)

The front cover picture illustrates the photophysical and practical properties of PXX (peri-xanthenoxanthene) as novel photocatalyst. A synthetic experiment is portrayed as a video game where you need to choose the right components to start your game: PXX has now been unlocked as a photocatalyst with high reducing power, moderate oxidizing power, high versatility and low cost. In this work, Bonifazi and co-workers demonstrate the use of PXX in a variety of synthetic transformations, from radical additions, to organocatalytic reactions, to nickel-catalysed cross couplings. Details can be found in the Research Article by Bonifazi and co-workers (C. Pezzetta, A. Folli, O. Matuszewska, D. Murphy, R. W. M. Davidson, D. Bonifazi, Adv. Synth. Catal. 2021, 363, 4740-4753; DOI: 10.1002/adsc.202100030)
