into the corresponding aromatic nitriles in high yields using molecular iodine and 1,3-diiodo-5,5-dimethylhydantoin, respectively, in aq ammonia. Similarly, primary alkyl halides were also converted into corresponding nitriles in moderate to good yields using molecular iodine and 1,3-diiodo-5,5-dimethylhydantoin in aq ammonia, although a long reaction time was required. The present reaction is a new
分别在氨水溶液中分别使用分子碘和1,3-二碘-5,5-二甲基乙内酰脲将各种苄基卤化物平稳并直接以高收率直接转化为相应的芳族腈。类似地,尽管需要较长的反应时间,但使用分子碘和氨水中的1,3-二碘-5,5-二甲基乙内酰脲也可以将中级伯烷基卤以中等到良好的产率转化为相应的腈。本反应是一种由苄基卤化物制备芳族腈的新方法,并且是一种在保留碳原子数的情况下将烷基卤化物转化为相应腈的新方法。
