Contraction of [pi]-Conjugated Rings upon Oxidation from Cyclooctatetraene to Benzene via the Tropylium Cation

We have serendipitously discovered a unique transformation of a cyclooctatetraene derivative 1 into a cycloheptatriene spirolactone 3 upon oxidation, which is the first such transformation reported in 60 years. Product 3 could be reversibly interconverted into the aromatic tropylium cation 3H+ by ac...
