The title compound 8 has been synthesized and the kinetic parameters of its aromatization have been measured. In the key-step of the synthesis g,6-dihydrobenzocyclobutadiene is used, a new and powerful diene that cycloadds along its axis.
A&l-act. Two isomers of Z,Z-9,10-bis(styryl)anthracene have been observed by 1H and 1% NMR spectroscopy. The t3C chemical shifts were assigned by the 1%tH HETCOR technique. The barrier to interconversion of these two isomers is measured to 18 kcal/mol. The syvn isomer forms a charge transfer complex
