Reaction Steps

A round bottom flask was charged with 4-iodobenzoic acid (3.0 g, 12.1 mmol) in chloroform (100 mL). To the solution was added thionyl chloride (5.0 mL) in chloroform (10 mL) and 2-3 drops of dimethylformamide (DMF). The slurry was heated at reflux for 2 hours. while monitoring the reaction through an oil bubbler. A clear solution of 4-iodobenzoyl chloride was obtained. The volatiles were removed and a colorless oil was obtained which solidified upon cooling.
