Abstract

Irradiation of the absorption band of an NAD (nicotinamide adenine dinucleotide) dimer analogue, 1-benzyl-1,4-dihydronicotinamide dimer, (BNA)₂, in acetonitrile containing a cyclopentadienyliron dicarbonyl dimer, [CpFe-(CO)₂]₂, results in generation of 2 equiv of the cyclopentadienyliron dicarbonyl anion, [CpFe(CO)₂]^-, accompanied by the oxidation of (BNA)₂ to yield 2 equiv of BNA⁺. The studies on the quantum yields, the electrochemistry, and the transient absorption spectra have revealed that the photochemical generation of [CpFe(CO)₂]^- by (BNA)₂ proceeds via photoinduced electron transfer from the triplet excited state of (BNA)₂ to [CpFe(CO)₂]₂.
