Gas phase thermolysis at 450 deg C of 7-acetoxynorbornadiene (1) or of 7-acetoxycycloheptatriene (2) yielded acetic acid and heptafulvalene (4) indicative of the intermediate formation of cycloheptatrienylidene (3).The latter rearranged to fulveneallene (8) on thermolysis at 600 deg C.The elimination of acetic acid could involve a tropylium/acetate-ion pair since ionic processes dominate in the similar elimination of acetic acid from the tricyclic acetate 20.
