  • Aminolysis of X-Substituted Phenyl Diphenylphosphinates: Effect of Amine Nature on Reactivity and Transition-State Structure

    日期:2009.4.17
    the reactions of 1a with secondary amines (βnuc = 0.38) and for those of 1a−i with piperidine (βlg = −0.66) but typical for reactions that proceed through a concerted mechanism. It has been concluded that aminolysis of 1a−i proceed through a concerted mechanism and the nature of amines does not affect the reaction mechanism. However, the reactions with primary amines have been suggested to proceed through
    据报道,动力学研究表明,在25.0±0.1℃下,将80摩尔%H 2 O / 20摩尔%二甲基亚砜中的X-取代苯基二苯基次膦酸酯(1a-i)进行氨解。2,4-二硝基苯基二苯基次膦酸酯(1a)与伯胺反应的布朗斯台德图与βnuc = 0.53呈线性关系。的反应中1A-I与乙胺也导致与β的线性布朗斯台德型情节LG = -0.81。这些βnuc和βlg值比先前报道的1a与仲胺的反应(βnuc = 0.38)和1a−i的值稍大。与哌啶(βlg = -0.66),但通常用于通过协调机制进行的反应。已经得出的结论是1a-i的氨解通过协同机制进行,并且胺的性质不影响反应机理。然而,已经建议在较大的βnuc和βlg值的基础上,与伯胺的反应通过较晚的过渡态(即,过渡态中更多的键形成和键断裂)进行。1a-i与乙胺的反应的Yukawa-Tsuno图在ρ= 2.24和r时表现出极好的线性相关性,这进一步支持了这种协调的机理。=

  • The α-Effect in Nucleophilic Substitution Reactions of Y-Substituted-Phenyl Diphenylphosphinates with HOO<sup>-</sup>and OH<sup>-</sup>
    作者:Hyo-Jeong Hong、Ae Ri Bae、Ik-Hwan Um

    Second-order rate constants ($k_HOO^-}$) for the nucleophilic substitution reactions of Y-substituted-phenyl diphenylphosphinates (4a-4i) with $HOO^-$ in $H_2O$ have been measured spectrophotometrically. The $\alpha}$-nucleophile $HOO^-$ is 10-70 times more reactive than the reference nucleophile $OH^-$ although the former is ca. $4pK_a$ units less basic than the latter, indicating the $\alpha}$-effect is operative. The Bronsted-type plot for the reactions of 4a-4i with $HOO^-$ is linear with $\beta}_lg}=-0.51$, a typical $\beta}_lg}$ value for reactions which were reported to proceed through a concerted mechanism. The Yukawa-Tsuno plot is also linear with $\rho}=1.40$ and r = 0.47, indicating that a negative charge develops partially on the O atom of the leaving group, which can be delocalized to the substituent Y through resonance interactions. Thus, the reactions have been proposed to proceed through a concerted mechanism. The magnitude of the $\alpha}$-effect (i.e., the $k_HOO^-}/k_HO^-}$ ratio) decreases linearly as the leaving-group basicity increases. It has been concluded that solvation effect is not solely responsible for the $\alpha}$-effect found in this study but the transition-state stabilization through an intramolecular H-bonding interaction is also responsible for the $\alpha}$-effect.
    用分光光度法测量了 Y-取代苯基二苯基膦酸盐 (4a-4i) 与 $HOO^-$$H_2O$ 中发生亲核取代反应的二阶速率常数 ($k_HOO^-}$)。$alpha}$亲核物 $HOO^-$的反应性比参考亲核物 $OH^-$ 高 10-70 倍,尽管前者的反应性约为 $4pK。$4pK_a$单位的碱性比后者低,这表明$α}$效应在起作用。4a-4i 与 $HOO^-$ 反应的勃朗斯特型曲线图是线性的,$\beta}_lg}=-0.51$,这是一个典型的$\beta}_lg}$值,据报道反应是通过协同机制进行的。Yukawa-Tsuno 图也是线性的,$\rho}=1.40$,r = 0.47,这表明在离去基团的 O 原子上产生了部分负电荷,该负电荷可通过共振作用分散到取代基 Y 上。因此,这些反应被认为是通过协同机制进行的。随着离去基团碱性的增加,$\alpha}$效应的大小(即$k_HOO^-}/k_HO^-}$比率)呈线性下降。研究得出的结论是,溶解效应并不是本研究中发现的 $\alpha}$ 效应的唯一原因,通过分子内 H 键相互作用实现的过渡态稳定也是 $\alpha}$ 效应的原因。
  • Analysis of Linear Free-Energy Relationships Combined with Activation Parameters Assigns a Concerted Mechanism to Alkaline Hydrolysis of X-Substituted Phenyl Diphenylphosphinates

    A kinetic study is reported for alkaline hydrolysis of X-substituted phenyl diphenylphosphinates (1 a-i). The Bronsted-type plot for the reactions of 1 a-i is linear over 4.5 pK(a) units with beta(lg)=-0.49, a typical beta(lg) value for reactions which proceed through a concerted mechanism. The Hammett plots correlated with sigma(o) and sigma(-) constants are linear but exhibit many scattered points
    动力学研究报道了X-取代的苯基二苯基次膦酸酯(1 ai)的碱性水解。1 ai反应的布朗斯台德型图在4.5 pK(a)单位上呈线性,其中beta(lg)=-0.49,这是通过协调机制进行的反应的典型beta(lg)值。与sigma(o)和sigma(-)常数相关的Hammett图是线性的,但表现出许多分散的点,而相应的Yukawa-Tsuno图则具有出色的线性相关,rho = 1.42和r = 0.35。r值为0.35表示离开组离开在速率确定步骤(RDS)中部分提前。由于进入的HO(-)离子比离去的芳基氧化物更碱性,并且核收性较差,因此排除了在RDS中发生离去基团与加成中间体的离去的逐步机理。还基于小beta(lg)值排除了解离(D(N)+ A(N))机制。随着离去基团中的取代基X从H变为4-NO(2)和3,4-(NO(2))(2),DeltaH ++从11.3 kcal mol(-1)降至9
  • Combined dual substituent constant and activation parameter analysis assigns a concerted mechanism to alkaline ethanolysis at phosphorus of Y-substituted phenyl diphenylphosphinates
    作者:Ik-Hwan Um、Jee Eun Park、Young-Hee Shin

    Second-order rate constants have been measured for reactions of Y-substituted phenyl diphenylphosphinates (1a–h) with EtO−K+ in anhydrous ethanol. A linear Brønsted-type plot is obtained with βLg = −0.54, a typical βLg value for reactions which proceed through a concerted mechanism. The Hammett plots correlated with σo and σ− constants are linear but exhibit many scattered points, while the corresponding Yukawa–Tsuno plot results in excellent linear correlation with r = 0.41. The r value of 0.41 indicates that the leaving group departs at the rate-determining step (RDS) whether the reactions proceed through either a concerted or a stepwise mechanism. However, a stepwise mechanism in which departure of the leaving group occurs at the RDS is excluded since the incoming EtO− ion is much more basic and a poorer leaving group than the leaving aryloxide. The ΔH‡ values determined in the current reactions are strongly dependent on the nature of the substituent Y, while the ΔS‡ values remain constant on changing the substituent Y in the leaving group, i.e., from Y = H to Y = 4-NO2 and Y = 3,4-(NO2)2. These ΔH‡ and ΔS‡ trends also support a concerted mechanism.
    测量了 Y 取代苯基二苯基膦酸盐 (1a-h) 与 EtO-K+ 在无水乙醇中反应的二阶速率常数。得到的布氏线性图为 βLg = -0.54,这是通过协同机理进行反应的典型 βLg 值。与 σo 和 σ- 常数相关的 Hammett 图是线性的,但表现出许多分散的点,而相应的 Yukawa-Tsuno 图则具有极好的线性相关性,r = 0.41。0.41 的 r 值表明,无论反应是通过协同机理还是逐步机理进行,离去基团都会在速率决定步骤(RDS)上离去。然而,由于进入的 EtO- 离子比离开的芳基氧化物碱性更强,离开基团的能力更弱,因此排除了离开基团在 RDS 发生时离开的分步机理。在当前反应中测定的 ΔH‡ 值与取代基 Y 的性质密切相关,而 ΔS‡ 值则在离去基团中的取代基 Y 发生变化时保持不变,即从 Y = H 到 Y = 4-NO2 和 Y = 3,4-(NO2)2 时保持不变。这些 ΔH‡ 和 ΔS‡ 趋势也支持一种协同机制。
