Insights into the elementary steps in Negishi coupling through kinetic investigations

The Negishi coupling has been widely applied in organic synthesis, while relevant mechanistic studies are relatively rare. To obtain an understanding of the fundamental steps in the Negishi coupling, oxidative addition, transmetalation and reductive elimination, the kinetic investigation has served as one of the most important strategies. In this review, insights into the elementary steps in the Negishi coupling through kinetic investigations are summarized.
