We report in the present paper the kinetic and mechanistic study of the oxidation of L-arabinose by
pyridinium chlorochromate C5
H5
NHCrO3
Cl, The reaction has been carried out in aqueous acetic acid
50 % (v/v) medium in presence of perchloric acid at constant ionic strength. The reaction has been found
to be fi rst order with respect to each of the oxidant and substrate under pseudo-fi rst order conditions.
The reaction is catalyzed by acid and follows a fi rst order dependence on H+
ion concentration. The
ionic strength variation has no effect on the reaction rate. The decreases in dielectric constant of the
medium increase the rate of reaction. A 1:1 stoichiometry is observed in the oxidation and the reaction
rate is not retarded by the addition of radical trapping agent acrylonitrile. Effect of temperature on
the rate of oxidation has been studied to show the validity of Arhenius equation and various activation
parameters have been computed. The products are identifi ed to be L-erythrose and formic acid. On
the observed facts a hydride ion transfer mechanism is proposed.
Keywords: L-arabinose, Kinetics, Mechanism, Pyridinium Chlorochromate.
Introduction
The kinetic of oxidation of organic compounds which contain a large number of functional groups
is of considerable interest from the mechanistic point of view and have been studied fairly well1-16
.
L-Arabinose is in fact more common in nature and is found in nature as a component of biopolymers
such as hemicelluloses and pectin. In view of this, kinetic and mechanistic studies on oxidation of
L-arabinose has been given a great deal of attention. Among halochromate of nitrogen containing
heterocyclic compounds, pyridinium chlorochromate17
is a versatile oxidizing agent for the effective
