Reactions of anhydrous CrCl3 with H2bpb and H2bpc in dimethylformamide and manganese(III) acetate with H2bpc in methanol, yielded the respective *xH2O, *H2O and complexes.The electrochemistry of the chromium(III) amide complexes has been studied by cyclic voltammetry.They exhibit reversible oxidation couples with E0 values ranging from 0.28 to 0.80 V vs. ferrocenium-ferrocene.Except for (1-) which has a quasireversible reduction couple at -1.97 V, the electrochemical reductions are irreversible.The complexes ClO4, and have been shown to catalyse olefin epoxidation by iodosobenzene.With , catalytic oxidation of alkanes by PhIO has also been observed.An oxygen-rebound mechanism involving a Mn(V)=O or a Cr(V)=O intermediate is proposed for the PhIO oxidation reactions.
