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.

The treatment of F-alkyl ketones with sodium diethyl phosphite in tetrahydrofuran at −10 to 0 °C gave high yields of 1-substituted F-1-alkenyl phosphates, which readily reacted with amidine or hydrazine derivatives at room temperature to afford the corresponding fluorinated pyrimidines or pyrazoles, respectively, in good to excellent yields.

102ChemInform Abstract Reaction of the olefins (II) or the alkynes (IV) with the perfluoroalkyl iodides (I) in the presence of Pd(0) produces the adducts (III) and (V) respectively.
