Abstract: The Friedel-Crafts acylation reactions of substituted benzene derivatives with substituted acid chlorides proceed smoothly in the presence of a catalytic amount of Envirocat EPZG, a novel supported reagent catalyst, based on montmorillonite K10 clay. This catalyst is eco-friendly, selective and reusable and hence provides a safer and a cost effective approach for large-scale production in industries. The present work involves synthesis of fifteen ketones by using fresh and reused Envirocat EPZG catalyst and a conventional catalyst for Friedel-Crafts reaction, anhyd. AlCl3. The yields of ketones with fresh Envirocat EPZG are always more than that obtained with anhyd. AlCl3. Envirocat EPZG has been reused for the number of reactions in a series, without much loss in its efficiency. Ketones having activating as well as deactivating groups on benzene ring have been synthesized in satisfactory yields.
