| 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. |
