摘要：
Perfluorocycloalkanesulfonic anhydrides decompose thermally to give bicyclohexyls, presumably by a homolytic mechanism. Reaction with iodine, sulfur, and benzene gives, respectively, the cyclohexyl iodide, disulfide, or benzene, the latter in poor yield. Upon extrapolation of NMR shifts to infinite dilution, only the CFI group gives an anomalous slope, attributable to reversal of RFI-to-IRF association. (C) 1998 Elsevier Science S.A.
