Abstract:
The kinetics of reaction between aliphatic ?-amino acids and 1,3-dichloro-5,5-dimethylhydantoin have been studied in aqueous acetic acid medium yielding aliphatic aldehydes as the end-products by the ring cleavage oxidation. The catalytic effect of acid in the reaction rate reveal an interaction between oxidants species H2O+Cl and substrates. The observed order of reactivity ?-amino acids (?-Glycine > ?-Alanine) was explained on the basis of conformational considerations. A plausible mechanism and rate law supported by thermodynamic parameters was discussed.
