Abstract

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.
