Two short synthetic pathways affording anti-[2.2](1, 6) azulenophane (3) via fluoride-induced l&eliminations from trimethylsilyl-tetraalkylammonium salts are described. The structural assignment of the title compound 3 is based on spectral data. Results from flash vacuum pyrolysis experiments suggest that 3 fractures at 620" C to generate the corresponding monomer, 1, 6-azulylene (l), a highly reactive polyene.
