Abstract
Mechanisms based on the 1,4‐migration of metal centers have been proposed to explain some interesting transition‐metal‐catalyzed organic transformations. Despite the lack of solid evidence for the real nature of this process, the 1,4‐metal migration reaction is proposed to proceed by the reductive elimination of trivalent intermediates for the Rh‐involved reactions and of tetravalent intermediates for the Pd‐catalyzed processes. These high‐valent organometallic species would be formed by the oxidative addition to CH and CX bonds. This minireview summarizes the results in this area.Keywords
