Electrochemical Screening and DFT Analysis of Acetylacetonate Metal Complexes in Organic Solvents.

Seven acetylacetonate (acac) metal complexes ranging from early transition metals to post-transition metals were examined by cyclic voltammetry in acetonitrile (MeCN), dichloromethane (DCM), tetrahydrofuran (THF), dimethyl sulfoxide (DMSO), and dimethylformamide (DMF). The electronic potential of any observed redox events is reported along with an analysis of the reversibility of those events across a range of scan rates. Group 8 compounds Fe(acac) Ru(acac) showed at least quasi-reversible reductions across all solvents while Ru(acac) also featured a reversible oxidation.
