  t-butanol containing potassium t-butoxide and in ethanol containing sodium ethoxide. The rates of the E2 reaction of the sulphur compounds are found to be 102–103 times as great as those of the corresponding oxygen analogues in both media. These rates can be correlated with Hammett σ values. The ρ values obtained for sulphur compounds are 1·98 and 2·14 in t-butanol and ethanol, while those for oxygen

  在含有叔丁醇钾的叔丁醇和含有乙醇钠的乙醇中，已经确定了碱催化消除一系列对位取代的β-苯基巯基乙基氯和相应的氧类似物的速率。硫化合物的E2反应速率为10 2 –10 3两种介质中对应的氧类似物的两倍大。这些比率可以与Hammettσ值相关。在叔丁醇和乙醇中，硫化合物的ρ值分别为1·98和2·14，而氧类似物的ρ值分别为1·33和1·50。与含氧化合物相比，含硫化合物的更快的动力学速率和较高的Hammettρ值表明3d轨道共振在这些含硫化合物的E2消除反应中很重要。讨论了速率和取代基作用的其他含义。
