  逐步酰基转移反应机理的证据：对硝基苯基取代的苯甲酸酯与氢氧化物和对氯酚的反应的非线性哈米特图

  摘要：

  为标题反应得到的哈米特地块表现出断裂，即ρ酰基值从2.21~2.44作为酰基取代基变强吸电子基团（降低至1.45~1.52 σ > 0.6）。哈米特曲线的这种断裂暗示了反应机理的改变，也为酰基转移反应的逐步机理提供了有力的证据。

  A kinetic study is reported for the reactions of 4-nitrophenyl X-substituted benzoates (1a-1) and Y-substituted phenyl benzoates (2a-1) with two anionic nucleophiles (OH(-) and CN(-)) and three amines (piperidine, hydrazine, and glycylglycine) in 80 mol% H(2)O-20 mol% dimethyl sulfoxide (DMSO) at 25.0 +/- 0.1 degrees C. Each Hammett plot exhibits two intersecting straight lines for the reactions of

  The magnitude of the α-effect for reactions of 4-nitrophenyl substituted benzoates with a pair of anionic nucleophiles is independent of the electronic nature of the acyl substituent, while the one for the corresponding reactions with a pair of neutral nucleophiles increases as the acyl substituent changes from a strong electron withdrawing substituent to electron donating ones.

  Second-order rate constants have been measured spectrophotometrically for the reactions of X-C6H4CO2C6H4-Y with a series of primary amines in H2O containing 20 mol% DMSO at 25.0 +/- 0.1 degrees C. The reactivity increases as the substituent (X and Y) becomes a stronger electron-withdrawing group. The sigma(+) constants give better Hammett correlation than sigma constants for the reactions of 4-nitrophenyl X-substituted benzoates with glycylglycine (glygly) and hydrazine (NH2NH3, indicating that the ground-state stabilization effect is unusually significant on the reaction rates. The reactions of X-C6H4CO2C6H4-Y with glygly and NH2NH2 appear to proceed through the same mechanism, but the degree of leaving-group departure and the negative charge developed in the acyl moiety at the rate-determining TS is considered to be more significant for the glygly system than the NH2NH2 system based on beta(1g) and rho(x) values. The magnitude of the alpha-effect is observed to be not always dependent on the beta(nuc) value but dependent on the electronic nature of the substituent X and Y, i.e., an electron-donating substituent increases the alpha-effect, while an electron-withdrawing one decreases the alpha-effect. The present study has led to the conclusion that the ground-state effect is important for the reaction rates but it is not solely responsible for the alpha-effect, and the intramolecular H-bonding interactions (4) are proposed for the cause of the increasing or decreasing a-effect trends observed in the present system.
