A novel method for the preparation of N-chloroaldimines from commonly available aromatic aldehydes has been developed. The reaction proceeded effectively by two steps: aldehydes were initially transformed into imines and then chloro-substitution with NaClO2 gave the N-chloroaldimines. This simple protocol allows for the preparation of a variety of aromatic N-chloroaldimines in moderate to excellent
已开发出一种从常用芳香醛制备 N-
氯醛
亚胺的新方法。该反应通过两个步骤有效进行:醛最初转化为
亚胺,然后用 NaClO2
氯代取代得到 N-
氯醛
亚胺。这种简单的方案允许以中等至极好的收率制备各种芳香族 N-
氯醛
亚胺,而无需分离
亚胺中间体。我们还发现
3-硝基
苯甲醛和
4-氰基苯甲醛在标准条件下直接转化为相关的
苯甲腈。
