Abstract
Publisher Summary This chapter presents an alternative to the classical Friedel-Crafts catalysis using heterogeneous catalysts such as zeolites as one believes them to be ultimate catalysts for the future production of aromatic ketones. The Friedel-Crafts acylation as well as the related Fries rearrangement of aromatics are methods of choice in today's organic chemistry for synthesizing aromatic ketones as reactive intermediates for the production of fine chemicals. The conventional method of preparation of these aromatic ketones is the homogeneous Friedel-Crafts acylation of aromatic hydrocarbons with carboxylic acid derivatives using Lewis acid or Bronsted acids (polyphosphoric acid, HF). For this purpose, stoichiometric to excess amounts of the catalyst are required for the reaction to proceed.
