Reactions of molybdenum(vi) with metal ion reductants

The reactions of aqueous H2MoO4 at low pH with titanium(ii), titanium(iii), europium(ii), vanadium(ii), and germanium(ii), as monitored at 430 nm, give biphasic profiles featuring a sharp rise in absorbance followed by a marked decrease (Fig. 1). The final product is the dimeric Mo(v) cation, [Mo2O4]2+, and the strongly absorbing intermediate is taken as a monomeric Mo(v) species. The molar absorbances of the transients from different reductants are not the same, nor are the rate laws governing the fadings. None of the decay curves exhibits evidence of a second order dependence on the transient. The kinetic behaviors of these systems are consistent with the intervention of successor complexes of the type, (formed by inner sphere reductions of Mo(vi)), which decompose, via first-order processes, to a monomeric Mo(v) species. The latter then experiences rapid dimerization, which is kinetically silent. The possibility that Ge(ii) bypasses the unstable tripositive state by reducing Mo(vi) to Mo(iv) (which then undergoes rapid Mo(vi)-Mo(iv) comproportionation) is considered.

Kinetics of oxidation of iodide by vanadium (V)

Kinetics of oxidation of iodide ion by VV under uncatalysed and RuIII catalysed conditions in aqueous perchloric acid medium have been studied. The reaction is first order in [VV] and first order in [I-]. With [H+], the reaction shows a complex behavior of 1.5 order till [H+] is 0.5 M and second order beyond that concentration. In the case of RuIII catalyzed oxidation, the reaction exhibits a dual character of first order and zero order in [VV]. The first order component shows 1.5 order in [I-] first order in III> and 1.5 order in [H+]. The zero order component shows first order in [I-], first order in [RuIII] and independent of [H+]. No catalysis has been observed with OsVIII. Suitable rate laws have been postulated based on the observations.
