Abstract
The invention relates to the synthesis of functional fluoro derivatives and more particularly that of perfluorinated aldehydes of the type R.sub.F -CHO where R.sub.F denotes a linear or branched perfluoroalkyl radical. A perfluoroalkyl iodide R.sub.F I is reacted over the zinc-copper metal couple, in the presence of a radical initiator, with an amide RCONR.sub.1 R.sub.2, R denoting a hydrogen atom or a methyl or ethyl radical, and each of R.sub.1 and R.sub.2 denoting a C.sub.1 -C.sub.4 alkyl radical.
