Direct propylene epoxidation by O2 is a challenging reaction because of the strong tendency for complete combustion. Results from the current study demonstrate that by generating highly dispersed and stabilized Cu+ active sites in a TiCuOx mixed oxide the epoxidation selectivity can be tuned. The TiCuOx surface anchors the key surface intermediate, an oxametallacycle, leading to higher selectivity...
Propylen‐Epoxidierung. Aktive Cu+‐Zentren auf einer Cu2O‐Oberfläche werden durch TiOx stabilisiert. Wie J. G. Chen et al. in der Zuschrift auf S. 12114 ff. zeigen, bildet das resultierende Mischoxid mit Propylen einen intermediären Oxametallacyclus und erhöht so die Selektivität der Propylen‐Epoxidierung.
