Electronic effects in 1,3-diaryl-1,3-diketone reduction potentials correlate with σ
The electrochemical reduction of aryl-substituted dibenzoylmethanes was studied in acetonitrile. They display one-electron couples that are chemically and electrochemically reversible at low concentrations. The formal potentials correlate with only one (σ) of the various Hammett parameters.
