N2 - An NAD dimer analogue, 10,10′-dimethyl-9.9′-biacridine [(AcrH)2]2] reduces dioxygen much more efficiently than the corresponding monomer, 10-methyl-9,10-dihydroacridine (AcrH2) in the presence of HClO4 and a catalytic amount of CoTPP+ (TPP = tetraphenylporphyrin) in acetonitrile to yield 10-methylacridinium ion and hydrogen peroxide. The mechanistic difference between (AcrH)2 and AcrH2 for the catalytic two-electron reduction of dioxygen is revealed based on the detailed kinetic studies.
