• The α-Effect in Hydrazinolysis of 4-Chloro-2-Nitrophenyl X-Substituted-Benzoates: Effect of Substituent X on Reaction Mechanism and the α-Effect

  Second-order rate constants ($k_N$) have been measured spectrophotometrically for the reaction of 4-chloro-2-nitrophenyl X-substituted-benzoates (6a-6h) with a series of primary amines including hydrazine in 80 mol % $H_2O$/20 mol % DMSO at $25.0^\circ}C$. The Br$\o}$nsted-type plot for the reaction of 4-chloro-2-nitrophenyl benzoate (6d) is linear with $\beta}_nuc}$ = 0.74 when hydrazine is excluded from the correlation. Such a linear Br$\o}$nsted-type plot is typical for reactions reported previously to proceed through a stepwise mechanism in which expulsion of the leaving group occurs in the rate-determining step (RDS). The Hammett plots for the reactions of 6a-6h with hydrazine and glycylglycine are nonlinear. In contrast, the Yukawa-Tsuno plots exhibit excellent linear correlations with $\rho}_X$ = 1.29-1.45 and r = 0.53-0.56, indicating that the nonlinear Hammett plots are not due to a change in RDS but are caused by resonance stabilization of the substrates possessing an electron-donating group (EDG). Hydrazine is ca. 47-93 times more reactive than similarly basic glycylglycine toward 6a-6h (e.g., the $\alpha}$-effect). The $\alpha}$-effect increases as the substituent X in the benzoyl moiety becomes a stronger electron-withdrawing group (EWG), indicating that destabilization of the ground state (GS) of hydrazine through the repulsion between the nonbonding electron pairs on the two N atoms is not solely responsible for the substituent-dependent $\alpha}$-effect. Stabilization of transition state (TS) through five-membered cyclic TSs, which would increase the electrophilicity of the reaction center or the nucleofugality of the leaving group, contributes to the $\alpha}$-effect observed in this study.

  二次速率常数（$k_N$）已通过分光光度法测定，用于4-氯-2-硝基苯基X取代苯甲酸酯（6a-6h）与一系列伯胺（包括80摩尔% $H_2O$/20摩尔% DMSO中的25.0°C下的联氨）的反应。当联氨被排除在相关性之外时，4-氯-2-硝基苯基苯甲酸酯（6d）反应的Br$\o}$nsted型图是线性的，$\beta}_nuc}$ = 0.74。这种线性Br$\o}$nsted型图是典型的反应，先前报道这些反应通过逐步机制进行，其中离去基团的排出发生在速率决定步骤（RDS）中。6a-6h与联氨和甘氨酰甘氨酸反应的Hammett图是非线性的。相比之下，Yukawa-TSuno图显示出极佳的线性相关性，$\rho}_X$ = 1.29-1.45，r = 0.53-0.56，表明非线性Hammett图并非由于RDS的变化，而是由于具有供电子基团（EDG）的底物的共振稳定化所导致。联氨对6a-6h的反应性大约是同样碱性的甘氨酰甘氨酸的47-93倍（例如，$\alpha}$效应）。随着苯甲酰基中取代基X成为更强的吸电子基团（EWG），$\alpha}$效应增加，表明通过两个N原子上的非键电子对之间的排斥来破坏联氨的基态（GS）并不是唯一导致取代基依赖的$\alpha}$效应的原因。通过五元环过渡态（TS）的稳定化，这将增加反应中心的亲电性或离去基团的离核性，有助于在本研究中观察到的$\alpha}$效应。

• A highly selective chemosensor for copper ion based on ICT fluorescence
  作者：Fang Ying Wu、Sheng Gen Cao、Cai Xia Xie

  日期：2012.5

  Simple structural compounds 1 to 3 were synthesized. The presence of Cu2+ resulted in the fluorescence and absorption spectra change of 1 and 2, which indicated that 1 and 2 showed a highly selective response to Cu2+ over other metal ions. However, 3 showed no selectivity for metal ions, which means that the compound could bind with several metal ions, such as, Ni2+, Zn2+, Cd2+, Hg2+, Pb2+, Fe3+, Mg2+, Ca2+, and Co2+, except Cu2+ and Ag+. The different spectral responses were attributed to the difference in binding sites for 1 and 3. (C) 2012 Fang Ying Wu. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
