Lewis Acid‐Catalyzed Ring‐Opening Alcoholysis of Cyclohexene Oxide: The Role of Open Metal Sites in the Bi(III)‐based Metal‐Organic Framework SU‐101

Von Wiley-VCH zur Verfügung gestellt

Cyclohexene oxide alcoholysis: SU-101 was applied for the Lewis acid-catalyzed ring-opening alcoholysis of cyclohexene oxide.


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.
