Mechanism of water oxidation by non-heme iron catalysts when driven with sodium periodate.

Iron tris(2-methylpyridyl)amine (TPA) and iron 1-(bis(2-methylpyridyl)amino)-2-methyl-2-propanoate (BPyA) salts are characterized as water oxidation catalysts (WOCs) using sodium periodate. Under the conditions used, these complexes serve as homogeneous WOCs as demonstrated via kinetic analysis and dynamic light scattering (DLS). The Fe(BPyA) salt serves as both a mononuclear and dinuclear cata...

The oxidation of phenylhydrazine by tyrosinase.

Tyrosinase was found to catalyze the oxidation of phenylhydrazine to phenol in a reaction that did not resemble those typically performed by tyrosinase. The kinetics of this reaction was investigated by measuring the initial velocity of the formation of phenol (25 °C). The values of k cat and K M for the oxidation of phenylhydrazine were obtained as 11.0 s(-1) and 0.30 mM, respectively. The gen...

Quantitative Determination of Dihydrostreptomycin by Periodate Oxidation.

Dihydrostreptomycin is produced commercially by the catalytic hydrogenation of streptomycin. The reaction involves the reduction of the aldehyde group in the streptose moiety of the streptomycin molecule to the corresponding primary carbinol group as evidenced by the failure of dihydrostreptomycin to react with carbonyl reagents or with alkali to produce maltol. As there are no chemical methods...
