Metal‐Organic Frameworks Supported Ruthenium Catalyst for Efficient Alkene Hydroesterification

In recent years, the hydroesterification of alkenes has garnered significant attention in the field of unsaturated compound functionalization. The current research efforts are predominantly focused on the development of highly efficient, stable, and recyclable catalyst systems. In this work, the mental‐organic framework supported Ru catalyst was designed for the hydroesterification of alkene. The Ru/MOF‐808 (Zr) catalysts feature ruthenium atoms dispersed in the framework, exhibiting high catalytic activity in the hydroesterification of styrene under mild reaction conditions. Notably, the addition of LiBr significantly enhanced the catalytic performance through interacting with Ru/MOF‐808 (Zr). The detailed characterization revealed that the stability of Ru species at lower oxidation state was crucial for achieving high activity. The in situ FT‐IR spectroscopy confirmed the reaction mechanism: styrene reacted with CO to form a key acyl intermediate, which subsequently reacted with activated MeOH. Furthermore, the catalyst exhibited excellent regenerability.
