A Stille cross-coupling reaction was developed that delivers for the first time trifluoromethyl-substituted homoallyl compounds from α-(trifluoromethyl)benzyl chlorides and allylstannanes. This reaction proceeds even with low catalyst loadings (1 mol%) vi

Dehydrofluorination of 1-aryl-1,2,2,2-tetrafluoroethanes (ArCHFCF 3) and 1-aryl-1-chloro-2,2,2-trifluoroethane (ArCHClCF3) using lithiumhexamethyldisilazide (LHMDS) in tetrahydrofuran (THF) at room temperature produced 1,2,2-trifluorostyrene and 1-chloro-2,2-difluorostyrene, respectively, in very good isolated yields. Dehydrofluorination of 1,2,2,3,3,3-hexafluoro-1-phenyl-propane (PhCHFCF2CF3) and 1,2,2,3,3,4,4,4-octafluoro-1-phenyl-butane (PhCHFCF2CF 2CF3) using LHMDS produced the corresponding substituted olefins (1-phenyl-1,2,3,3,3-pentafluoroprop-1-ene and 1-phenyl-1,2,3,3,4,4,4- pentafluorobut-1-ene) in good yield and high E-selectivity. Dehydrofluorination of 1-chloro-1-phenyl-2,2,3,3,3-pentafluoropropane (PhCHClCF2CF 3) and 1-chloro-1-phenyl-2,2,3,3,4,4,4-heptafluorobutane (PhCHClCF2CF2CF3) produced a mixture of the corresponding E and Z olefins (PhCClCFCF3 and PhCClCFCF 2CF3) in good yield.

Gas-phase stabilities of 1-aryl-2,2,2-trifluoroethyl cations were determined based on chloride-transfer equilibria. The substituent effect was analyzed based on the LArSR Eq., giving a remarkably high r of 1.53 and a ρ of -14.6.

The catalytic phosphorylation of α-polyfluoroalkylbenzyl alcohols by bis(polyfluoroalkyl) chlorophosphates is a convenient method for the synthesis of various bis(polyfluoroalkyl)(α-polyfluoroalkylbenzyl) phosphates, including those having donor substituents in the benzene ring.It was shown that in the series of p-methyl-α-trifluoromethylbenzyl phosphates p-CH3C6H4CH(CF3)OP(O)XY (where X, Y = Cl, CF3CH2O), the ability to act as O-alkylating agents with respect to polyfluorinated alcohols is a common characteristic, and the alkylating ability increases symbatically with increase in the overall electron-acceptor strength of the X and Y substituents at the phosphorus atom.
