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

Abstract

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)
