Reactions of organocopper compounds. Part I

Abstract

Perfluoroheptylcopper(I), perfluoropropylcopper(I), and hexafluorotrimethylenedicopper(I) react with halogeno-olefins to yield the corresponding polyfluoroalkyl-substituted derivatives. Similar reactions with phenylethynyl-copper(I) and phenylthiocopper(I) are reported. The role of copper and its co-ordination to organic species are illustrated by the reactions of butyl chloride and benzyl chloride with butylthiocopper(I) and copper(I) cyanide in the absence and presence of ligands which readily bind copper. A rationalisation of the reactions of halogen on an sp² carbon atom is advanced.
