Acetamide/SO2Cl2 reagent has been developed for effective Friedel-Craft's acylation of aromatic compounds. Acylation of aromatic compounds with acetamide/SO2Cl2 was much more effective and faster than analogous (acetamide/SOCl2) and (acetamide/POCl 3) reagents even under conventional conditions. However, microwave and ultrasonic assisted reactions afforded high yields of products in very short reaction times (30-40 min under sonication and 3-4 min under microwave assisted conditions).
