Abstract

Catalytic Friedel–Crafts acylation of 2(3H)-benzoxazolone and 2(3H)-benzothiazolone has been achieved using aluminum chloride (AlCl3) supported on silica gel as catalyst under solvent free conditions. The obtained Ketones were char-acterized and confirmed by physical and spectroscopic data. The catalyst is recycla-ble and stable at room temperature, and the reaction protocol is simple, cost-effective, and gives good isolated yield with high purity.
