Abstract

Acylation of aromatic compounds with carboxylic acids smoothly proceeded at 190–230° C in the presence of zeolite catalysts under microwave irradiation to give aromatic ketones efficiently. H–Y (SiO2/Al2O3= 30–80) and H–beta (25) zeolites were active for the acylation reaction, giving the aromatic ketones in good yields. Carboxylic acids such as hexanoic and butyric acid smoothly underwent the acylation, while propionic acid showed somewhat ...
