Abstract

original image

ΔpH important for chemoselectivity: The relationship between absolute proton concentration (pH value), the change in the pH value (ΔpH) and catalytic performance in important iron-catalyzed selective oxidation reactions is demonstrated (see figure). It is clearly shown that an increased proton concentration led to higher catalyst activity and a small ΔpH during the reaction is responsible for improved selectivity.
