Physical Organic Studies on Bimolecular Reactions in Reversed Micelles: Addition of Cyanide Ion to the N-Methyl-3-carbamoylpyridinium Ion in Hexadecyltrimethylammonium Bromide Reversed Micelles

The bimolecular reaction of cyanide (CN-) ion with N-methyl-3-carbamoylpyridinium (S+) ion, in the water pool of the reversed-micellar system water/ hexadecyltrimethylammonium bromide (HTAB)/ chloroform-isooctane (3:2, v/v) has been studied at various temperatures (15-40 deg C) by measuring spectrophotometrically the decrease of the absorption due to S+ (265 nm) and the increase of the absorption due to the addition product (340 nm).The results of the reaction series were examined throughout with respect to the molar ratio of water to HTAB, R.Since the rate and equilibrium constants of the bimolecular reaction are affected by the method in which the concentrations of reactants are defined or by fixing the extent of reaction space, the water pool is assumed to be the sole reaction space and the rate and equilibrium constants in the water pool, k2w and Kw, which are based on the modified concentrations of the reaction species, have been evaluated.It is found that terms of k2w and Kw, the smaller the value of R, the more the addition reaction is enhanced.From the relationships between Kw and k2w vs. temperature, the standard and activation enthalpies of reaction, ΔH and ΔH, respectively, have been calculated.The behavior of ΔH and ΔH as well as Kw and k2w is found to differ in reactions which have R below and above ca.3.To explain the enhancement of the reaction due to the specific field effect of the water pool and the retardation of the reaction due to electrostatic interactions among S+ ions, the involvement of CN- and HTAB ions is proposed.The differing behaviour in the reactions is more clearly manifested in the thermodynamic and kinetic diagrams of enthalpy vs. entropy, which give separate plots corresponding to R both below and above ca.3.In addition, the effect of varying the CN- ion concentration is discussed and is found to be consistent with the situation described above.
