with various benzyl sulfides in the presence of equimolar amounts of cupric chloride and zinc chloride was investigated. For example, in the case of benzylation of anisole with 4-benzylthiopyridine, o- and p-benzylanisoles were obtained in 79% yield in the presence of cupric chloride and zinc chloride. On the other hand, when the reaction was carried out in the presence of cupric chloride alone, the
研究了在等摩尔量的氯化铜和氯化锌存在下,芳香族化合物(如苯甲醚、间二甲苯、甲苯和苯)与各种苄基硫化物的苄基化反应。例如,在苯甲醚与 4-苄基硫代吡啶苄基化的情况下,在氯化铜和氯化锌存在下以 79% 的产率获得邻和对苯甲醚。另一方面,当仅在氯化铜存在下进行反应时,苄基苯甲醚的产率低。氯化铜和氯化锌的类似活化已成功应用于芳香族化合物与苯甲醛二乙硫缩醛的反应以及芳香族化合物与 1,2-双(酰硫基)乙烷的酰化反应。
