Studies in fluorinated 1,3-diketones and related compounds Part X. Synthesis of some new polyfluorinated 1,3-diketones,their copper 1,3-diketonates and spectral studies

The reaction of tetrafluoro-1,2-diiodobenzene with tellurium yields an oil which, on treatment with bromine yields perfluorotelluranthrene- 9,9,10,10-tetrabromide. The latter is reduced by sodium sulfide to perfluorotelluranthrene. The crystal structure of perfluorotelluranthrene is reported.
