  摘要：

  氯和二氯苯酚已在非质子传递溶剂中用硫酸和SO 3磺化。在用浓硫酸水溶液进行磺化反应中，磺酸异构体的分布主要取决于羟基取代基的邻位和对位和活化作用。这也是使用不超过1.0当量的SO 3的非质子磺化反应的决定因素。当使用大量的SO 3时，磺化异构体的分布越来越多地通过相应的苯基硫酸氢盐的额外磺化来确定，其中-OSO 3 H取代基是失活的，主要是对-（进而邻）指挥。

  日期：——

  The nine chloro- and dichloroanisoles have been sulfonated with sulfuric acid. The observed sulfonic acid isomer distributions are determined mainly by the ortho- and para- directing effect of the methoxy substituent. In the reaction with sulfuric acid, the initially formed chloro- and dichloroanisolesulfonic acids are demethylated to give the corresponding phenolsulfonic acids. Demethylation occurs

  九种氯苯甲醚和二氯苯甲醚已用硫酸磺化。观察到的磺酸异构体分布主要取决于甲氧基取代基的邻位和对位作用。在与硫酸的反应中，将最初形成的氯代和二氯茴香醚磺酸脱甲基，得到相应的苯酚磺酸。脱甲基化仅在甲氧基取代基在空间上受邻氯和/或邻位阻碍的情况下发生-磺基取代基。2，3-和3，5-二氯茴香醚与发烟硫酸的反应最初分别产生4，6-和2，4-二磺酸。通过直接的磺基甲基化或通过原脱甲基化，随后进行硫酸化，将二磺酸转化为相应的硫酸氢盐。2,3-二氯-4,6-二磺基苯基硫酸氢环化成1,3,2,4-苯并二恶二硫辛2,2,4,4-四氧化物4。

  日期：1996.1.1

  The hydrolysis reactions of several title esters in water at 60 degrees C follow the rate law k(obs) = (k(a) + k(b)[OH(-)])/(1 + a(H)/K(a)), where K(a) is the ionization constant of the hydroxy group of the ester and k(b) is the second-order rate constant for the S(N)2(S) attack of hydroxide ion on the ionized ester. Hammett and Brønsted correlations are consistent with a previous proposal that the

  几种标题酯在60°C的水中的水解反应遵循速率定律k（obs）=（k（a）+ k（b）[OH（-）]）/（1 + a（H）/ K（ a）），其中K（a）是酯的羟基的电离常数，k（b）是氢氧根离子对离子化酯的S（N）2（S）攻击的二级速率常数。Hammett和Brønsted相关性与先前的建议一致，即与k（a）有关的机制是分离的。发现k（a）值与取代醌的氧化还原平衡常数之间存在异常关系：这一发现进一步支持了与k（a）有关的途径的解离性质。
