Versuchsvorschrift

Examples 1-5 are repeated but using ethyl propionate, propionyl iodide and ethyl iodide in place of methyl acetate, acetyl iodide and methyl iodide, respectively. Propionic anhydride is produced in corresponding manner, with propionyl iodide also being produced in the procedures of runs 2-5.
