Vlasov, Vladislav M. published the artcileSubstituent effects in substrates on activation parameters in the bimolecular nucleophilic reactions in solution, Recommanded Product: 4-Iodo-3-nitrobenzonitrile, the publication is New Journal of Chemistry (2010), 34(12), 2962-2970, database is CAplus.
Changes of the activation parameters, ÎHâ?/sup> and ÎSâ?/sup>, in the SN2, SNAr and acyl-transfer reactions with charged and neutral nucleophiles in various solvents were correlated with Ï constants of the substituents in the aromatic ring of the substrates. The resultant δÎHâ?/sup> and δÎSâ?/sup> reaction constants are linearly related for variations of substituents at the substrate. Correlation of δÎHâ?/sup> vs. δÎSâ?/sup> allows one to estimate the contribution of changes of the internal enthalpy, δÎHâ?/sup>int, to the enthalpy reaction constant, δÎHâ?/sup>, which gives a single linear dependence on the Hammett Ï reaction constants for all bimol. nucleophilic reactions. The deviations from dependence of δÎHâ?/sup>int vs. Ï can be interpreted in terms of changes of the transition state structure or reaction mechanism. The results obtained show that the substituent effects in the substrates and nucleophiles on the charge development in the transition state are governed by the magnitude of δÎHâ?/sup>int.
