Cathodic reduction of the tropylium cation in methylene dichloride
Abstract
The tropylium cation in methylene dichloride solution is reduced by a one-electron step at the D.M.E. and the rotating platinum electrode with the same half-wave potential. The tropyl radicals thus formed dimerise irreversibly, electrolysis in an e.s.r. spectrometer showed that this reaction is very fast, and large-scale amperostatic electrolysis proved the formation of bitropyl.
