The nucleophilic reactivities of substituted thiophenolates were determined by following the kinetics of their reactions with a series of quinone methides (reference electrophiles) in DMSO at 20 °C. The experimentally determined second-order rate constants were analyzed according to the Mayr-Patz equation log = ( + ) to derive the nucleophile-specific reactivity parameters and for ten thiophenolate ions.
通过在20°C下于二甲基亚砜(DMSO)中跟踪一系列取代硫酚盐与醌甲基化物(参考亲电试剂)的反应动力学,测定了取代硫酚盐的亲核反应活性。根据迈尔 - 帕茨方程log = ( + ) 对实验测定的二级速率常数进行分析,以得出十种硫酚盐离子的亲核试剂特异性反应参数 和 。
