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

achieved by reaction with either elemental fluorine or Selectfluor™, an electrophilic fluorinatingreagent of the N–Fclass. An electrophilic mechanism is envisaged. On prolonged reaction, the strongly acidic reaction medium that is formed upon substitution of hydrogen by fluorine when Selectfluor™ is used as the fluorinatingreagent, promotes loss of fluoride from the initial fluorinated product.
