The invention relates to the shape selective acylation of an organic compound. In particular, the invention describes a process for such acylation wherein the process comprises reducing the number of surface acid sites on at least a portion of the surface of a zeolite and acylating the organic compound in the presence of the zeolite. The organic compounds used in the invention include, for example, olefins, aromatic hydrocarbons, aromatic heterocyclic compounds, and phenolic compounds wherein the organic group may be substituted or unsubstituted. The zeolite may be any natural or synthetic zeolite with a unidimensional or multidimensional network, for example a two-dimensional, or three-dimensional network, or any molecular sieve with structural features similar to these.
