Versuchsvorschrift

To a solution of 3,4-diacetoxy-ω-chloroacetophenone (2) (1.08 g: 4 mMol.) in acetone (11 ml) keeping at 0° C. is added sodium iodide (1.2 g: 2 Eq.), and the mixture is stirred at room temperature for 1 hour. The reaction mixture is diluted with ethyl acetate, washed with water, dried, and concentrated under reduced pressure to give 3,4-diacetoxy-ω-iodacetophenone (3) (1.38 g).
