Electron transfer. 50. Reduction of carboxylato-bound chromium(V) with hydrazine

Solutions of the chromium(V) complex sodium bis(2-ethyl-2-hydroxybutyrato)oxochromate(V) (I) oxidize hydrazinium ion smoothly. Each mole of N2H5+ consumes 2 mol of Cr(V), yielding N2 and a Cr(III) product exhibiting ion-exchange behavior and an electronic spectrum consistent with a chelated monocarboxylato derivative of (H2O)4CrIII. Kinetic results, obtained at pH 3.3-4.6 in the presence of added carboxylato ligand, point to a pair of two-electron transactions. The first of these, an oxidation to N2H2, is rate determining, whereas the second, the conversion to N2, is rapid. Reactions, carried out in trimethylacetate buffers, are inverse first order in added 2-ethyl-2-hydroxybutyrate and are also inhibited by H+. The algebraic form of the rate law (eq 3 in text) is consistent with a two-path mechanism (eq 5-9), both components of which involve preliminary rapid and reversible loss of a carboxylato ion from the Cr(V) oxidant. The resulting monocarboxylato intermediate then may undergo reduction either directly through (outer-sphere) reaction with N2H5+ or, alternatively, via formation of a precursor complex, assembled with loss of H+. The appearance of only one Cr(III) reaction product suggests that the Cr(V) species attacking N2H2 in the final rapid step(s) has the same ligand environment as that attacking N2H5+ in the rate-determining steps.
