✦ Synopsis

The osmium(VII1)-catalyzed oxidation of D-proline and L(-)-methionine by alkaline hexacyanoferrate(II1) has been studied spectrophotometrically. The reactions follow kinetics different from those of the oxidation of many amino acids investigated earlier, being first order in hexacyanoferrate(II1) and osmium(VII1). The order in proline or methionine and OHdecreases from unity to zero at higher concentratiom of proline or methionine and OH-, respectively. A mechanism consistent with the kinetic data is proposed and discussed.

Kinetics of oxidation of phenylhydrazine and p-bromophenylhydrazine by hexacyanoferrate(I1If in acidic medium have been studied. The reactions follow similar kinetics, being first order with respect to both hydrazine and hexacyanoferrate(II1) and inverse first order with respect to the hydrogen ion.
