Electrochemical reduction of [Ru(pbn)(bpy) 2 ] 2+ ( 1 , pbn=2‐(2‐pyridyl)benzo[ b ]‐1,5‐naphthyridine, bpy=2,2′‐bipyridine) in an acidic solvent gives [Ru(pbnH 2 )(bpy) 2 ] 2+ ( 2 ), which releases the hydrogen as “hydride” (see scheme). This catalytic system reduces substrates (for example, acetone) with two electrons and protons from water, and thus operates in a similar way to the NAD + /NADH redox couple.
