correlation of ΔH# with ΔS# is sometimes misleading and
the evaluation of β by means of the above equation lacks
statistical validity. Exner advocates an alternative method
for the treatment of experimental data [40], he proposed
that β can be evaluated from the equation:
NBP to give aldehyde, NHP, CO2, and Br−, in agreement
with the experimental observed stoichiometry. The deduced
rate law from the reaction scheme was also consistent with
kinetics of the reaction. Future studies on the Ru(III) chlo-
ride catalyzed oxidation of other biological relevant amino
acids and peptides by NBP would also be of interest.
β = T1T2(b − 1)/T2b − T1.

A plot of log k2 at 303 K versus log k1 at 308 K gave
isokinetic temperature as 348.22 K. Higher values of β
(348.22 K) than the experimental temperature (303 K) indi-
cates that the rate is governed by the enthalpy of activation

The title reaction exhibited first-order dependence on NBP
for all amino acid and followed zero-order kinetics for gly-
cine (Gly), alanine (Ala), valine (Val) while, leucine (Leu)
showed fractional order dependence on the rate of reaction.
The Ru(III) chloride showed a catalytic effect on the reac-
tion and followed first-order kinetics with respect to [Ru
(III)] at a low concentration range in each case, and nega-
tive effect of perchloric acid were observe for the oxidation
of Gly, Ala, Val and Leu. Addition of KCl positively influ-
enced the rate of oxidation of Gly, Ala, Val and Leu, while
effect of added electrolyte (ionic strength) for the oxidation
of Gly, Val, Ala, show negligible effect, whereas negative
effect was observed for the oxidation of Leu. D had no sig-
nificant effect on the rate for the oxidation of Gly, Ala, Val,
while the rate of oxidation of leu increases with decrease
in dielectric constant of the medium. Addition of reduced
product of oxidant, i.e. NHP, had no significant effect on
oxidation velocity of Gly, Ala, Leu, but in case of Val it
showed negative effect [3, 36, 37].

Conclusions
Oxidation of Leu by NBP in perchloric acid medium was
found to be very sluggish, but oxidation became facile in
the presence of Ru (III) chloride catalyst. NBP without
proton attached and RCH(NH3+)COO− were the reac-
tive species of oxidant and Leu, respectively. Among the
various species of Ru(III) chloride in an acidic medium,
[RuCl3(H2O)2OH]− was determined to be the catalyzed
species. In the proposed reaction scheme, the equilibrium
of [RuCl3(H2O)2OH]− and Leu gave C3, which on reac-
tion with NBP give C4, which on further reaction gives C5
through a slow rate-determining step. The species formed
was responsible for oxidation of Leu. In the Scheme 1,
each molecule of Leu consumed more than two moles of
