摘要：

Rate constants for the one-electron cathodic reduction of tris(acetylacetonato)chromium(III) were determined by pulse polarographic and cyclic voltammetric techniques at 23 degrees C in 10 organic solvents (acetonitrile, propylene carbonate, gamma-butyrolactone, N,N;dimethylformamide, N,N-dimethylacetamide, dimethylsulphoxide, N,N-diethylformamide, hexamethylphosphoric triamide, N-methylformamide and formamide). It has been shown that the observed solvent dependence of the rate constant is mostly caused by solvent relaxation dynamics, but the donor-acceptor interactions between solvent and solute should not be neglected.
