A simple, novel method for the preparation of trifluoromethyl iodide and diiododifluoromethane

Abstract
CF3l was synthesized in high yields by treatment of XCF2CO2Me(X = Cl or Br) with iodine in the presence of potassium fluoride and copper iodide; if Kl was used instead of KF under similar conditions, CF2l2 was obtained in moderate yields.
