  exo,exo-4,8-Ethenopolyfluoro-2,6-dioxaperhydroindacenes. Unusual Alkenes Flanked with Fluorine Atoms

  摘要：

  Unusual alkenes, exo,exo-4,8-etheno-1,1,3,3,5,5,7,7-octafluoro-2,6-dioxaperhydro-s-indacene (1) and exo,exo-4,8-etheno-1,1,3,3-tetrafluoro-2,6-dioxaperhydroindacene (2), as well as their nonfluorinated analogue 3 were synthesized. The structures of 1 and 3 have been determined in the solid state by X-ray crystallography and of all three compounds in solution by H-1, F-19, and C-13 NMR spectroscopy. The chemical. properties of compounds 1-3 were investigated and compared, The double bond in fluorinated polycycloalkenes 1 and 2 was found to be totally inert toward bromination, hydrogenenation, and oxidation with m-chloroperbenzoic acid and ozone. This is in contrast to nonfluorinated indacene 3, which behaves like a normal alkene, readily adds bromine and hydrogen, and reacts with oxidants. The only successful chemical transformation of I was achieved by treatment with Mn2O7, which led to oxirane 15 and rearranged pentacyclic acetal 16. An interesting skeletal rearrangement occurred in the course of bromination of 3 leading to bicyclic tetrabromo derivative 12. High chemical inertness of polyfluoroindacenes 1 and 2 has been attributed mainly to through-space electronic interactions of the double bond with proximal fluorine atoms.

  摘要：

  Dehydrobromination of trans-3,4-dibroma-7,7,9,9-tetrafluoro-8-oxa-cis-bicyclo[4.3.0]-nonane (1) was studied under a variety of conditions. In alkaline media, 3-bromo-7,7,9,9-tetrafluoro-8-oxa-cis-bicyclo[4.3.0]non-3-ene (2) and/or 1,3,3-trifluoro-1,3-dihydroisobenzofuran (3) were formed in ratios depending on the nature of the base and its concentration. Vacuum pyrolysis of 1 gave 7,7,9,9-tetrafluoro-8-oxa-cis-bicyclo[4.3.0]nona-2,4-diene (7) as the main product.
