Preparation of the all-syn isomer of 1,2,3,4-tetrafluorocyclohexane is reported; X-ray structural studies shows a conformation with two of the C-F bonds oriented 1,3-diaxial to each other and (19)F-NMR reveals a through space diaxial (4)J(FF) coupling constant of 29 Hz.

pushing all fluorines toward the other face. The reaction also pushed fluorine toward the same face as nitrogen and oxygen in heterocycles such as indole and benzofuran. Science, this issue p. 908 Rhodium catalysis in a nonpolar solvent produces cyclic fluorocarbons with all the fluorines on the same face of the ring. All-cis-multifluorinated cycloalkanes exhibit intriguing electronic properties. In particular
