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 K<sub>10</sub> 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. AlCl<sub>3</sub>. The yields of ketones with fresh Envirocat EPZG are always more than that obtained with anhyd. AlCl<sub>3</sub>. 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.
