Acepleiadylene-5,8-dione (1) and acepleiadylene-5,6-dione (2) have been synthesized by the stepwise oxidation of 6,7-dihydrocycloheptacenaphthene-5,8-dione (4) and 7,8-dihydrocycloheptacenaphthene-5,6-dione (21) derived from compound (4), respectively.The reduction potentials of compounds (1) and (2) were determined by cyclic voltammetry which showed that E1=-0.50 V and E2=-0.84 V for the former, and E1=E2=-0.29 V for the latter.Spectral and electrochemical data suggest that both diones (1) and (2) are annulenediones with a vinyl cross-link. 5,8- and 5,6-Dihydroxyacepleiadylene,(9') and (22'), exist in their keto-forms, 6,7-dihydrocycloheptacenaphthylene-5,8-dione (9) and 7,8-dihydrocycloheptacenaphthylene-5,6-dione (22), respectively.
