  Kinetics of the reaction of substituted 4-nitrophenyl benzoates with benzenethiol in the presence of potassium carbonate in dimethylformamide

  摘要：

  The effect of the substituent nature on the rate and activation parameters of transesterification of a series of 4-nitrophenyl benzoates with benzenethiol in dimethylformamide in the presence of potassium carbonate was studied by the competing reaction method. In all cases, change of the Gibbs energy of activation is determined mainly by variation of the enthalpy of activation. 4-Nitrophenyl benzoates having electron-withdrawing substituents in the benzoyl fragment were found to fit an isokinetic relation with an isokinetic temperature beta of 318 K. Enthalpy-entropy compensation effect was observed in the reactions with all the examined 4-nitrophenyl benzoates. The relation between the reactivity and polarizability of nucleophilic center in S- and O-nucleophiles is discussed.

  N，N'-二异丙基碳二亚胺对羧酸与胺和酚的酰胺化和酯化反应：在水中形成酰胺和酯键的新方法

  摘要：

  本研究报告了N，N'-二异丙基碳二亚胺（DIC）作为绿色溶剂在水中成功合成了两个重要而丰富的官能团“酯和酰胺”。可以使用具有高官能团耐受性的各种基材。在短的反应时间后以高收率获得产物。该方法为在水性介质中形成酯和酰胺键提供了有效，经济，简单且非常温和的方案。此外，这项工作不仅可能导致环境友好的系统，而且还将提供水中有机化学的新方面。

  abundant functional groups "ester and amide" by N,N′-diisopropylcarbodiimide (DIC) in water as a green solvent. A wide range of substrates could be employed with high functional group tolerance. The products were obtained in high yields after short reaction times. This method provides an efficient, economic, simple and very mild protocol for ester and amide bond formation in aqueous media. In addition, this
