Abstract The effect of zeolite structure (pore size, channel connectivity) and concentration of active sites on the activity of zeolites in ferrocene acylation with acetic acid derivatives was investigated. The conversion of ferrocene under identical reaction condition increases in the sequence medium-pore zeolites < large-pore zeolites and one-dimensional zeolites < three-dimensional zeolites. Ferrocene conversion increases with increasing concentration of aluminum in the framework. Both Broensted and Lewis acid sites contribute to the reaction mainly depending on the acid strength.
