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

Fluoroalkenes of general structure R-CF=CF-CF3 (2a, R = cyclopentyl and 2b, R = cyclohexyl), prepared in high yield in two steps from hexafluoropropene and the appropriate cycloalkane, react with oxygen, carbon, and hydrogen nucleophiles to give R-CX=CF-CF3 derivatives (X = H, OR, R, Ar). Reaction of fluoroalkenes 2a and 2b with allylic alkoxides gave products arising from Claisen rearrangement, providing

A general, efficient approach for the synthesis of fluorocarbon iodides and di-iodides bearing hydrocarbon groups is described and the synthetic utility of these new systems is demonstrated in reactions with thiols.
