之前发布有关此反应的文章,主要介绍是加入锰还原三价铬使二价铬再生,参与反应。1977 年Tamejiro Hiyama和Hitoshi Nozaki首先发现此反应,之前的方法是还原三价铬盐得到二价铬盐直接进行反应,只不过之前的底物是烯丙基卤代物,到1983年底物扩展到烯基和芳基卤代物,后来发现是由于反应中混入了镍杂质的原因。1986年Yoshito Kishi 在哈佛大学进行polytoxin全合成的时候发现了氯化镍在此反应中的作用。
Nozaki-Hiyama反应
2016-03-25 有机合成
铬诱导下卤代烷和醛进行偶联的氧化还原反应。此反应的优点就是对醛有很高的化学选择性,缺点就是利用大量的有毒的铬盐。
此反应的新方法是只需要催化量的二价铬盐,加入锰进行还原使催化剂再生。
