  Abstract: The pyridinophane complex   [Mn(Py2N2)(H2O)2]2+ catalyzes the disproportionation of H2O2 in   aq. soln. over a wide pH range. Kinetic investigations reveal an   induction period, which is proposed to involve the formation of a   hydroperoxo intermediate, as well as evidence for catalyst   self-inhibition. A catalytic cycle involving mononuclear   intermediates has been proposed. Spectroscopic investigations   under turnover conditions are consistent with this proposal and   show that the resting state of the catalyst is a mononuclear MnII   complex. The robustness of the catalyst is evidenced by its   ability to achieve turnover nos. of 58000 in aq. soln. [on   SciFinder(R)]
