Abstract
Abstract SU‐101 was screened for the acid‐catalyzed ring‐opening alcoholysis of cyclohexene oxide. Results indicated access to open metal sites within SU‐101, a fundamental requirement (Lewis acid Bi +3 sites) for this reaction. In addition, SU‐101 exhibited high chemical stability, demonstrated by retaining its crystalline structure after the reaction. The cyclohexene conversion was estimated to be 99.8, 96.8, and 14.3 % at 40 °C for methanol, ethanol, and propanol, respectively. Also, SU‐101 demonstrated an outstanding catalytic cyclability performance for five cycles without losing catalytic activity.
