REACTIVITE DES PERFLUOROIODOALCANES AVEC LES CARBONATES ET PYROCARBONATES D'ALCOYLES EN PRESENCE DE COUPLE METALLIQUE ZINC-CUIVRE
Perpluoroalkyl iodides RFI, in dissociating solvents, in the presence of zinc-copper couple give perfluoroorganic compounds RFZnI, which reac with alkyl carbonates and pyrocarbonates to give perfluorocarboxylic acids and perfluorocarboxylis esters of industrial interest.

REACTION DES ORGANOMAGNESIENS FLUORES AVEC LES CYANATES. PREPARATION DE NITRILES PERFLUORES.
The condensation of fluorinated Grinard reagents with phenyl cyanate produces perfluorinated nitriles.The isolation of an ester in the case of ethyl cyanate shows the existence of an imidic intermediate.
