Rates of reaction of a series of sulphones, p-Me·C6H4·SO2·[CH2]n·Br (n= 3–6) with sodium ethoxide in ethanol and with potassium t-butoxide in t-butyl alchol have been measured. Three types of reaction occur, namely substitution (ethoxide reactions only), elimination, and cyclisation. Quantitative analysis of the products allows dissection of the overall rate constants into the respective rate constants
一系列砜p- Me·C 6 H 4 ·SO 2 ·[CH 2 ] n ·Br(n = 3-6)与乙醇中的乙醇钠和叔丁基中的叔丁醇钾的反应速率酒精已被测量。发生三种类型的反应,即取代(仅乙醇反应),消除和环化。产物的定量分析允许将每个系统中每种反应类型的总速率常数分解为各自的速率常数。
