Abstract
The quasi-reversible one-electron electrooxidation of the 1,2,3,4,5,6,7-hepta(methoxy-carbonyl)cycloheptatrienide anion in MeCN at 22°C gives a radical whose ESR spectrum consists of seven lines with splittings from six protons with an intensity ratio of 1: 6: 15: 20: 15: 6: 1, which likely corresponds to a substituted bicyclo[3.2.0]heptadienyl structure.
