The kinetics of the title reaction have been studied in the pS+ range 4.0–12.0, at various temperatures. The logarithmic kinetic constants show excellent linear free energy correlations with σ and σn for the pS+- independent and pS+-dependent ranges, respectively. The susceptibility constants obtained (p+0.85 and +1.75, at pS+ 4.50 and 10.00, respectively) show that a larger negative charge is developed
标题反应的动力学进行了研究,该p小号+范围4.0-12.0,在各种温度下。对数动力学常数显示出与σ和σ优良线性自由能相关Ñ用于p小号+独立和p -小号+分别依赖性范围,。所获得的磁化常数(分别为p +0.85和+1.75,分别为p S + 4.50和10.00)表明,在碱催化的反应途径的过渡态中,比未催化的p S产生更大的负电荷+-独立路线。
