Hydrogenation of a Rhodium Peroxido Complex by Formate Derivatives: Mechanistic Studies and the Catalytic Formation of H2O2 from O2

Hydrogenation of dioxygen: The rhodium peroxido complex 1, which can be prepared from 2 and dioxygen, can be reduced with dihydrogen sources to yield hydrogen peroxide. In a catalytic experiment, hydrogen peroxide is produced from dioxygen and ammonium formate under ambient conditions in the presence of 1 (see scheme).
