A study on the oxidation of N,N-dimethylaniline and other alkylated anilines by dioxygen, air, and hydrogen peroxide catalyzed by several labile Fe complexes in acetonitrile was carried out. N,N-dimethylaniline (DMA) was oxidized to N-methylaniline and formaldehyde as well as to N-methylanilide. Formaldehyde and the excess of substrate underwent condensation reaction to produce 4,4′-methylenebis(N,N-dimethylaniline). Small quantities of N-methylformanilide and formanilide were also formed during oxidation of N,N-dimethylaniline and N-methylaniline, respectively. The system was very labile even in the presence of bpy as a ligand and it was difficult to formulate the nature of the reactive species. However, the results confirmed that Fe(III) was reduced by the substrate to Fe(II), which interacted with substrate and activated dioxygen for demethylation process.

The aquation of Fe(bpy)32+ (bpy = 2,2'-bipyridyl) was studied in aqueous hydrochloric acid at a range of pressure between 1 and 2070 bar.Activation volumes (ΔV) in 1.0 MHCl (+12.3 cm3mol-1), 0.01 M HCl (+14.8 cm3mol-1), 1.0 M DCl (+13.3 cm3mol-1) and 0.01 M HCl (+16.3 cm3mol1-) were determined.A mechanism involving a significant positive contribution to ΔV arising from a low-spin high-spin preequilibrium is proposed.The minor effect of the deuterium solvent isotope on ΔV is consistent with this proposal.
