TRANSITION-METAL COMPLEX CATALYZED POLYFLUOROALKYLATION. II. NOVEL AND CONVENIENT ROUTE TO 3-POLYFLUOROALKYLPROP-1-ENES THROUGH THE REACTION OF POLYFLUOROALKYL HALIDES WITH ALLYLSILANES
The reactions of polyfluoroalkyl halides with allylsilanes catalyzed by iron or ruthenium carbonyl complexes give 3-polyfluoroalkylprop-1-enes in good yields under mild conditions.
Synthesis of fluorinated brassinosteroids based on alkene cross-metathesis and preliminary biological assessment
Three types of brassinosteroid analogues with perfluoroalkylated side chains were synthesized by using alkene cross-metathesis of a brassinosteroid derivative bearing a terminal alkene moiety with different (perfluoroalkyl) propenes. The presence of the d

Perfluoroalkylation through cross-metathesis between alkenes and (perfluoroalkyl)propenes
A new approach to perfluoroalkylated compounds based on cross-metathesis between perfluoropropenes and terminal alkenes has been developed. The reaction is catalysed with high efficiency and selectivity by the Hoveyda-Grubbs second-generation catalyst under mild reaction conditions. The method is applicable to a wide range of compounds, such as vinylaromatics, isoprenoids and saccharides. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

Synthesis of functionalized long-chain perfluoroalkanes from methyl halodifluoroacetates: a process of difluorocarbene insertion into copper-carbon bonds
Treatment of XCF2CO2Me (X = Cl, Br) with organic halides in the presence of KF and catalytic amounts of CuI at 80-120 deg C for 3-8 h in DMF gave long-chain perfluoroalkylated compounds which are considered to be former by the insertions of CF2(..) into carbon-copper bonds.

Process for preparing polyfluoroalkyl-substituted compounds
A process for preparing a perfluoroalkyl-substituted compound is disclosed. The process comprises reacting a halopolyfluoroalkane having 1 to 20 carbon atoms with a compound selected from the group consisting of (1) a substituted or unsubstituted ethylene, (2) a substituted or unsubstituted acetylene and (3) a substituted or unsubstituted allylsilane, in the presence of a metal-carbonyl complex of the metal of the Group VIII of the Periodic Table. Alternatively, the reaction between the halopolyfluoroalkane and the substituted or unsubstituted allylsilane is effected under radical generating condition.
