Mc. Brown et al., PRESSURE AND PH-DEPENDENCE OF THE KINETICS OF DECARBOXYLATIVE DECHLORINATION OF N-CHLORO-L-ALANINE, International journal of chemical kinetics, 28(11), 1996, pp. 791-797
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. (C) 1996 John Wiley & Sons.
