Abstract : The tetrabromo and tetrachloro derivatives of three parent compounds-bisphenol A, hexafluoroacetone bisphenol, and tetrafluorodichloroacetone bisphenol were prepared. Elemental analyses were good in general and strongly indicated that the compounds were tetrahalogenated. Nuclear magnetic resonance studies proved that the compounds contained four symmetrical halogens. Infrared studies conclusively proved, by analogy with known model compounds, that the halogens were in the 2,6 rather than the 3,5 position. The melting points of the tetrabromo derivatives were, in general, considerably higher than those of the parent compounds, but in two instances the tetrachloro derivatives gave lower readings than the parent compounds. The reason for this difference is not known. (Author)
