Zeolite Shape-Selectivity in the gem-Methylation of Aromatic Hydrocarbons

A glove for the purpose: The kind of olefins obtained from methanol in zeolites is strongly dependent on specific combinations of the intermediate organic hydrocarbon‐pool species and zeolite topology (see picture). If the cage is too large, neutral species are favored over reactive cations. If the...

Summary:A glove for the purpose: The kind of olefins obtained from methanol in zeolites is strongly dependent on specific combinations of the intermediate organic hydrocarbon‐pool species and zeolite topology (see picture). If the cage is too large, neutral species are favored over reactive cations. If the cage is too small, transition‐state‐shape selectivity poses severe limitations on the reactivity of bulkier species.
