Attempts to localize the double bonds of the benzene ring in a Kekule-like structure have been made with some success by the groups of Vollhardt [57] and of Frank and Siegel [58]. This was reminiscent of the Mills-Nixon effect predicted in the 1930 s, although the partial localization has nothing to do with the tautomeric equilibrium in benzene argued by Kekule. [Pg.10]
