    Epoxidation of Trans-Stilbene to Produce Trans-Stilbene Oxide

    Li Z, et al. Chemical Engineering Journal, 2022, 429: 132149.

    Trans-stilbene is a typical olefin often used as a probe molecule to evaluate the activity of catalysts.
    The efficient catalyst systems for the epoxidation of trans-stilbene
    · Cobalt oxide catalyst can be used for trans-stilbene epoxidation reaction with tert-butyl hydroperoxide epoxidation for 20 hours to obtain the corresponding epoxide, with a conversion rate of 99% and a yield of 97%.
    · The cobalt-substituted TUD-1 mesoporous material was subjected to trans-stilbene epoxidation under a high O2 pressure of 2.76 MPa to obtain trans-stilbene oxide with a conversion rate of 93% and a selectivity of 91%.
    · Constructing palladium single atoms on defective boehmite (γ-AlOOH) nanoleaves as laboratory-stable catalysts. The catalyst exhibits excellent catalytic efficiency in the epoxidation of trans-stilbene to produce trans-stilbene oxide (TOF: 416 /h; conversion: 84%; selectivity: 99%), as well as excellent Recyclability and scalability.
