Abstract
The LFER equation log k = s(f)(E(f) + N(f)) was used to derive the nucleofuge specific parameters (N(f) and s(f)) for dimethyl sulfide in the series of aqueous alcohols, using the S(N)1 solvolysis rate constants obtained for X-substituted benzhydryl dimethyl sulfonates 1-5. The slope parameters (s(f)) are practically independent of the solvent used, while N(f) parameters slightly decrease as the polarity of the solvent increases.
摘要
该 LFER 方程 log k = s(f)(E(f) + N(f)) 被用于从一系列醇水溶液中二甲硫醚的 S(N)1 溶剂解速率常数 1-5 推导离去基团参数 (N(f) 和 s(f))。斜率参数 (s(f)) 实际上与所用溶剂无关，而 N(f) 参数随着溶剂极性的增加略有减小。
