(Chemical Equation Presented) New reaction conditions are described that enable the direct arylation of pentafluorobenzene with sterically encumbered aryl bromides and aryl chlorides. These reactions occur in high yield and under mild conditions. Notably, the reactions can be performed at 80°C in isopropyl acetate with a catalyst generated by the in situ mixing of Pd(OAc)2 and S-Phos. The enhanced scope of these transformations should further reduce the need to use pentafluorophenylboronic acid in the construction of perfluoroarenes.

Bis(pentafluorophenyl)ditellurium Te2(C6F5)2 and the three new furan derivatives 2- and 3-pentafluorophenylfuran and 2,5-dihydro-2-pentafluorophenylfuran are prepared by irradiating a mixture of Te(C6F5)2 and furan.Te2(C6F5)2 reacts with elemental mercury to yield Hg(TeC6F5)2.From the reactions of Tex(CF3)2 with Tex(C6F5)2 (x = 1, 2) equilibria are formed with the unsymmetrical compounds CF3TexC6F5.The syntheses, NMR, and mass spectra of these new compounds are described.
