H2O2 generation by decamethylferrocene at a liquid | liquid interface

Hydrogen peroxide generation at a liquid|liquid interface occurs with a yield of 20 % with respect to the concentration of reducing agent (decamethylferrocene). The liquid|liquid interface supplies electrons from the reducing agent and protons from the aqueous phase to drive the reduction of O2 into H2O2, which is extracted into the aqueous phase during the course of reaction (see picture; DCE=1,2-dichloroethane).
