The one-pot reaction of Mn(OAc)3 with two equivalents of 6-(pyridine-2-ylhydrazonomethyl)phenol (Hphp) in methanol leads to a unique leuco-verdazyl-type ring. The remarkable cyclodimerization reaction is proposed to involve a number of one-electron oxidative steps mediated by Mn3+ ions, as well as a very uncommon 1,2-radical aryl migration and a nucleophilic attack of the solvent, i.e. methanol.
