The reaction of polyfluoroaromatic organozinc compounds with oxalylchloride in DMF proceeds involving the Vilsmeier–Haack reagent with the formation of polyfluoroaromatic aldehydes as the major products. The use of CuI makes it possible to increase the yield of the target aldehydes.

Organozinc compounds of the general formula ArFZnX (X = Cl, ArF) were synthesized by reactions of Zn with chloropolyfluoroarenes and of Zn/SnCl2 with polyfluoroarenes. Polyflorinated organozinc compounds reacted with allyl chloride and allyl bromide to give the corresponding allyl-substituted polyfluoroarenes. The reactions with allyl chloride were carried out in the presence of copper(I) salts (CuCl or CuI).
