Reactions of Per(chloro, fluoro)ethanes with Aryloxide and Alkoxide Ions — Evidence for Chlorophilic Attack on CCl Bonds

The synthesis of aryl‐ and alkyl per(chloro, fluoro) ethyl ethers 2 is achieved by reaction of nucleophiles ROK with the substrates 1 (X, YCl, F). This is the first confirmed example for the attack of oxygen nucleophiles on the CCl bond. The ethers 2 are only obtainable with difficulty by others routes. equation image
