Mn. Khan et al., Effects of cationic micelles on the rate of intramolecular general base-catalyzed reaction of ionized phenyl salicylate with DL-proline, REACT KIN C, 69(1), 2000, pp. 83-90
Pseudo-first order rate constants (k(obs)) Obtained for the reaction of ion
ized phenyl salicylate (PS-) with anionic DL-proline (Prl(-)) at a constant
[NaOH] and [CTABr] (where CTABr represents cetyltrimethylammonium bromide)
and 35 degrees C, show a linear increase with increasing total concentrati
on of Prl(-). Nucleophilic second-order rate constants (k(n)(obs)) for the
reactions of Prl(-) with PS- reveal a nearly 5-fold decrease with the incre
ase in [CTABr] from 0.0 to 0.01 M.
