• Infrared spectra were recorded on either a Perkin Elmer Model 1420 infrared spectrometer or a Nicolet MXS FT IR as thin films or nujol mulls. NMR spectra were obtained in CC14, DCC13, or Me2SO - d6 solutions [(CH3)4 SI internal standard] at 60 MHz with a Varian EM-360 spectrometer. All boiling points and melting points are uncorrected and melting points were recorded on a Fisher-Johns melting-point apparatus

• When polyfluoroalkoxylation was desired, 2.2–3.0 equivalents of sodium hydride and 2,2,2-trifluoroethanol were used relative to the amount of the dihalobenzene substrate
