Abstract
The synthesis of aromatic ketones containing benzene ring, naphthalene ring or aromatic heterocycle in the presence of zeolite catalysts has been discussed. The replacement of the classical acid catalysts mainly AlCl 3 or HF by a zeolite diminishes the environmental problems. Different acylating agents are used acid chlorides, anhydrides or carboxylic acids. The mechanism of the acylation in the presence of zeolite catalysts is supposed to include acylium cation as electrophilic species. BEA zeolite is most studied.
