“…Term A in eq. (35) arises from the possible contribution of reactions (21) and (25). If KI is computed by assuming reaction (21) to be the only active pathway, a value higher than k z is obtained, therefore reaction (25) is responsible for the reaction path independent of acidity in eq.…”

The kinetics and mechanism of oxidation of iminodiacetic acid and N-methyliminodiacetic acid by aquasilver(I1) and Ag(II)-2,2'-bipyridine complexes has been investigated. The results are discussed with reference to the active reaction pathways, the equilibrium quotient of the title reactions, the protolytic equilibria which involve the oxidizing complex, and the intrinsic self-exchange rates of the oxidants.

“…This treatment gave hydrolysis equilibrium constants Kh = 0.32 f 0.14M at 22.OoC and y = 5.95M [ 3 ] , and 0.35M at 22.0"C and y = 4.OM [17]. Values ranging between 0.10 and 0.70 are also quoted at y = 5.6M [25]. More recently the addition of a hydroxyl radical to Ag+, using pulse radiolysis, has been investigated [26]:…”

“…The oxidations of phosphorus compounds have been studied with a variety of oxidants such as Bi(V), chloramine T, OH radicals, Ce(V), Ag(I), Ag(II), V(V), and AuCl 4 – . Formation of M–O–P intermediates as well as outer-sphere redox processes has been proposed.…”

Oxidation of Phosphorus Centers by Ferrate(VI): Spectral Observation of an Intermediate

et al. 2012

The kinetics and mechanism for the oxidation of phosphite, hypophosphite, phenylphosphite, and trimethylphosphite by ferrate(VI) are reported. Hypophosphite is rapidly oxidized to phosphite which is slowly oxidized to phosphate, trimethylphosphite is oxidized to trimethylphosphate, and phenylphosphite is oxidized phenylphosphate. (18)O induced shifts of the (31)P NMR signals support oxygen transfer from ferrate(VI) to the phosphorus center during the oxidation process. Deuteration of the hydridic hydrogens in hypophosphite and phosphite resulted in significant kinetic isotope effects on the reaction rates. It is proposed that ferrate(VI) acts as a two-electron oxidant in conjunction with oxide transfer coupled with phosphorus hydrogen bond breaking for phosphite and hypophosphite and simple oxygen transfer for trimethylphosphite and phenylphosphite.
