Abstract
1,9-Dimethyldibenzo[b,f] pentalene (18) was oxidized and reduced chemically and electrochemically to the respective dication and dianion. The parent hydrocarbon dibenzo[b,f] pentalene (17) also formed the respective dication and dianion. The dication and dianion showed aromatic diatropicity. The NMR characteristics are discussed in terms of the aromaticity vs. charge effects and the validity of the peripheral model is presented. The electrochemical parameters are discussed in relation to the electronic character of these systems.
