Cover Feature: Stability of a Silica‐Supported Second Generation Hoveyda‐Grubbs Catalyst Under Atmospheric Conditions: Experimental and Computational Studies (ChemCatChem 10/2023)

The Cover Feature illustrates the crucial role of storage conditions of silica-gel-supported 2nd generation Hoveyda-Grubbs catalyst. The glass shield on the spaceship protects the catalyst from air and moisture. In their Research Article, C. R. Apesteguía, S. E. Vaillard and co-workers show that after exposure to atmospheric conditions, O2 and H2O degrade the immobilized catalyst, compromising its applicability in olefin metathesis reactions. In order to retain long term stability the catalyst should be stored under controlled conditions. More information can be found in the Research Article by C. R. Apesteguía, S. E. Vaillard and co-workers.
