Abstract

The inside cover picture of a waterfall stream illustrates the continuous synthesis of various epoxides from olefins, with hydrogen peroxide as an oxidant, catalyzed by titanium silicalite‐1 (TS‐1). This reaction is applicable to the epoxidation of more than 20 olefins and the only co‐product is water. As a typical example, 4‐phenyl‐1,2‐epoxybutane was continuously synthesized in over 90% yield for more than 150 hours, and ICP‐MS/MS observations showed that little or no Ti loss from TS‐1 was observed. Details can be found in the Communication by Yoshihiro Kon and co‐workers (Y. Kon, T. Nakashima, Y. Makino, H. Nagashima, S. Onozawa, S. Kobayashi, K. Sato, Adv. Synth. Catal. 2023, 365, XXXX–XXXX; DOI: 10.1002/adsc.202300181).
