Aromatic polyfluoro-compounds. Part LIV. Copper-assisted nucleophilic displacement reactions of pentafluorohalogenobenzenes

Abstract

Copper-assisted nucleophilic displacement reactions of pentafluorohalogenobenzenes have been investigated; in some cases exclusive halogen replacement occurs, and in others fluorine displacement and halogen reduction are observed. The effects of solvent and added ligands, notably thiourea, on the course of the reaction have been studied and a theory developed to explain the results observed.
