Abstract
Trifluoromethyl iodide reacts with aryl halide in the presence of copper powder to give aryltrifluoromethane derivatives in a fairly good yield. This newly observed reaction is applicable to heterocyclic halides as well as benzene derivatives. Activities of halides are in the following order of readiness : iodide>bromide>chloride. Effects of solvents and natures of copper were examined.
