Aldehydes R-F(CH2)(m)CHO (R-F=n-CnF2n+1) have been prepared in good yields by oxidation of the corresponding alcohols using inexpensive and safe oxidants such as phenyliodine (III) diacetate and trichloroisocyanuric acid in the presence of 2,2.6,6-tetramethyl-1-piperidinyloxyl free-radical (TEMPO) as a catalyst.

A series of perfluoroalkylenamines of formula RFCF2CHCHNR2 has been obtained by the addition of secondary amines to perfluoroalkylethynes. Only the E isomer is formed. The dominant feature of their chemistry is the lability of the allylic C-F bonds, which is responsible for their instability and for the fact that acid hydrolysis yields mainly the enaminoketones RFCOCHCHNR2, a reaction which provides
