Addition of carbon tetrachloride to 3,3,4,4-tetrafluorohexa-1,5-diene

Abstract

The free-radical reaction of carbon tetrachloride with 3,3,4,4-tetrafluoro-1,5-hexadiene is described. Initiation of the chain process by a variety of redox-transfer systems has been studied. The cyclic isomeric monoadducts have been shown to possess four-, five-, six-, and seven-membered ring structures. The extent of rearrangement observed in the products is greatly influenced by metallic salt additives and by the solvent. However, the solvent effect is not observed in the presence of some copper(II) species.
