Preparation of perfluoroalkane carboxylic and sulphonic acid derivatives by the action of metallic couples on perfluoroalkyl iodides in dimethyl sulphoxide
Abstract
Perfluoroalkyl iodides react with carbon dioxide and sulphur dioxide, in the presence of zinc–copper type metallic couples in dimethyl sulphoxide, to give the corresponding carboxylic and sulphonic acids derivatives in 40–80% yields.
