Kinetics of oxidation of threonine by N-chlorosuccinimde using chloro complex of Rh (III)‎

Abstract EN

Rh(III) chloro complex as homogeneous catalyst has been used in the oxidation of threonine by N-chlorosccinimde (NClS) in acid medium.

The reaction shows first order kinetics with respect to NClS and zero order in threonine concentrations, the reaction also shows first order kinetics with respect to Rh(III).

The reaction product [succinimide] was added to the reactions and had no effect on the rate of oxidation of threonine by NClS using Rh(III).

Changing ionic strength, dielectric constant and chloride ion of the medium has no effect on the rate of oxidation.

H2OBr+ and [Rh(H2O) Cl5]-2have been suggested to be the reactive species of NClS and Rh(III) chloride at this pH.

The rates were determined at four different temperatures and the activation parameters were evaluated.

Aldehyde have been identified to be the oxidation products of the reaction.
