between neophyl kΔ substrates and 2-adamantyl tosylate. The pattern of dispersion could not be interpreted in terms of nucleophilic solvent assistance. The response to the solvent polarity (m value for each binary solvent series) was significantly lower for both the methoxy and the unsubstituted derivatives than the m = 1.0 for the limiting kc solvolysis, and appreciably lower for the methoxy derivative
2-苯基-2-甲基丙基和2-(对甲氧基苯基)-2-甲基丙基对甲苯磺酸盐的溶剂分解速率在多种溶剂中测定,并基于Winstein-Grunwald方程分析溶剂效应。溶剂对新植物溶剂分解的影响未能给出与 2-金刚烷基 YOT 参数的单一线性相关性。Neophyl kΔ 底物和甲苯磺酸 2-金刚烷基酯之间的相应二元溶剂系列存在分散行为。分散模式不能用亲核溶剂辅助来解释。甲氧基和未取代衍生物对溶剂极性(每个二元溶剂系列的 m 值)的响应显着低于限制 kc 溶剂分解的 m = 1.0,并且甲氧基衍生物明显低于未取代衍生物。
