Abstract
The kinetics of decarboxylative dechlorination of N-chloroalanine were studied at 25 degrees in aqueous HCl solutions covering the pH range 1.4 to 2.8. These data were compared with literature results, and were interpreted in terms of first-order reactions of the cationic, unchar ged, and anionic forms of the reactant. Pressure effect studies on the reaction of the anionic species yielded a volume of activation estima te of + 50 +/- 3 cm(3) mol(-1). This result is consistent with a conce rted fragmentation process.
