研究氯化亚铜催化的月桂烯氢氯化反应的产物分布和反应机理,考察了催化剂和稀释剂对产物分布的影响。结果表明:(1)月桂烯的氢氯化反应生成月桂烯基氯、芳樟基氯、橙花基氯、香叶基氯和。α-松油基氯5种单氯化物,产物中3种烯丙基型氯化物的含量约达到90%;(2)月桂烯的氢氯化反应是通过共轭双键吸附在催化剂表面上,并与吸附的氯化氢形成表面活化络合物进行的,该表面活化络合物经两个共振结构的碳正离子中间体分别生成芳樟基氯、橙花基氯和香叶基氯。并对提出的反应机理进行了讨论。
The product distribution and reaction mechanism of cuprous chloride catalyzed myrcene hydrochlorination were investigated. The effects of catalyst and diluent on product distribution were investigated. The results showed that: (1) The hydrochlorination of myrcene produced myrcenyl chloride, linalyl chloride, neryl chloride, geranyl chloride. α-terpinene chloride five kinds of monochloride, the product of three kinds of allyl chloride content of about 90%; (2) myrcene hydrochlorination by conjugate double bond adsorbed on the catalyst surface And forming a surface-activated complex with the hydrogen chloride adsorbed, the surface-activated complex generating linalyl chloride, neryl chloride, and geranyl chloride via the two carbenium intermediates of the resonating structure, respectively. The proposed reaction mechanism was discussed.
