Infrared spectra were taken on Perkin-Elmer Model X99 spectrophotometer and the absorptions are reported in wave numbers (ad). Mass spectra were obtained on a Nuclide 12-90-G instrument. Melting pointa were determined on a Thomas-Hoover capillary melting point apparatus and are uncorrected. Elemental analysis was performed by MultiChem Laboratories. l, l, l-Tri-chloro-3, 3, 3-trifluoroacetone was obtained from Fluke Chemical
