Abstract A new synthesis of aromatic sulfurpentafluoride compounds is described. Subsequent elaboration of the aromatic rings in the presence of the sulfurpentafluoride group is also discussed for a variety of common synthetic methods. This paper also describes ab initio electronic structure calculations of 3- and 4-aminophenylsulfurpentafluoride, compared with 3- and 4-aminobenzotrifluoride, and presents X-ray crystal structures of two aromatic sulfurpentafluoride derivatives.

γ-Ray or peroxide initiated reactions of acyclic and cyclic alkanes with hexafluoropropene are described. A variety of perfluorocarbons and polyfluorinated alkenes, di-enes and a tetra-ene were synthesised from these polyfluoroalkylated alkanes. Elimination of hydrogen fluoride gives fluorinated alkenes, with unusual kinetic control of product formation and further fluorinations gave novel perfluorocarbons. X-Ray crystallography established structures of some isomers and NMR spectroscopy was used principally to establish the structures of others.

A new telogen, I(CF2CFCl)nl (n= 1) and its telomers (n= average 6) are obtained by irradiation of mixtures of iodine and Chlorotrifluoroethylene.
