Azulenes by Vacuum Pyrolysis of Halotricyclo4,6>decadienes

Double addition of halocarbenes or -carbenoids to cyclooctatetraene yields the title compounds 2.Pyrolysis of these (700 deg C, 0.01 mbar) gives azulenes of varying substitution patterns (4, 5, 6, and/or 7) which carry one substituent in each ring.Structure assignments follow from 1H NMR spectroscopy, sometimes after electrophilic introduction of the trifluoroacetyl residue.Nucleophilic substitutions of azulenes with two halogen atoms (giving compounds 8 or 9) occur only in the 7-membered ring; only 4b and CuCN yield some 11 in addition to 10.

9-PHENYLBICYCLONONATETRAENYL ANION A NEW DIATROPIC 10 ?-ELECTRON SYSTEM
