New Efficient Palladium-Catalyzed Perfluoroalkylation of Carbon-Carbon Multiple Bonds with<i>F</i>-Alkyl Iodides. An Expedient Route to<i>F</i>-Alkylated Alkyl and Alkenyl Iodides
A variety of alkenes and alkynes efficiently undergo the perfluoroalkylation with F-alkyl iodides in the presence of a catalytic amount of tetrakis(triphenylphosphine)palladium(0) in hexane to give good yields of the corresponding F-alkylated alkyl and alkenyl iodides, respectively.

Addition of polyfluoroalkyl halides to alkynes and alkenes bearing a variety of substituents is effected by the catalysis of iron, cobalt and ruthenium carbonyl complexes to give the corresponding adducts in good to excellent yields under mild conditions.
Two new perfluoroalkylated phthalocyanine derivatives were synthesised and characterised in order to investigate the effects of the fluorophobic/fluorophilic interactions on their mesophase and electronic properties. Both compounds exhibit columnar mesomorphism and the thermal stability of the columnar phase is enhanced by over 20 °C as the number of fluorinated carbons increases, probably due to the
