摘要
在过渡金属催化的交叉偶联反应中,有机硅、锡化合物作为偶联亲核试剂已经广为人知,然而同族的锗元素研究却相对较少。锗亲核试剂的偶联反应最初只是简单地证明了锗作为一种"偶联元素"的可行性,但逐步发现的优异性质使得锗试剂已经受到越来越多的关注。本文从锗试剂的结构分类出发,介绍这些锗片段引入有机体系的方法及相应锗试剂的交叉偶联反应。
Organosilane and organostannane compounds have been well-known as nucleophilic fragments in transition metal catalyzed cross-coupling reactions. However, organogermanium is less familiar to us in such case. Cross-coupling of germanium nucleophiles initially only verified germanium itself as a possible ‘cross-coupling element’, gradually showed its unique behavior, which attracted more concentration on these reagents. This article is comprised of the introducing methods and properties in cross-coupling reactions of these germanium fragments by means of their structure classification.
