Solvent effects on the Hammett ρ value for the cathodic reduction of substituted benzophenones were determined. The electrochemistry of a series of 11 compounds was studied in acetonitrile, acetone, dimethyl sulphoxide, propylene carbonate, N , N ‐dimethylformamide, N , N ‐dimethylacetamide, N , N ‐diethylformamide and hexamethylphosphoric triamide. The ρ values for the reversible one‐electron transfer are described by the Lewis acid‐base model ρ = − 0.006 AN + 0.003 DN + 0.391, where AN = solvent acceptor number and DN = solvent donor number.
