Selective Catalytic Cross‐Cyclotrimerization En Route to 1,4‐Diborylated Benzenes and Their Synthetic Transformations. Front Cover Picture: (Adv. Synth. Catal. 7/2023)

The front cover picture illustrates the Ru-catalyzed [2+2+2] cyclotrimerization of “Bpin-acetylene” with internal alkynes furnishing selectively 1,4-diborylated benzenes. Judicious transformations of Bpin groups can provide a plethora of functionalized arenes such as terphenyls, terephthalates, chromanes, quinones, and hydroquinones (exemplified by natural compounds mirandamycin and violaceloid C). Details can be found in the Communication by Martin Kotora and co-workers (A. A. Fadeev, G. Manca, M. Kotora, Adv. Synth. Catal. 2023, 365, 965–970; DOI: 10.1002/adsc.202201337).
