Abstract

Herein, we report the gold-catalyzed aryl-alkenylation of unactivated alkenes with alkenyl iodides and bromides employing ligand-enabled gold redox catalysis. The present methodology followed the π-activation pathway rather than the migratory insertion pathway, which is predominant in other transition metal catalysis such as Pd, Ni, Cu, etc. Detailed mechanistic investigations such as 31P NMR, deuterium labeling, and HRMS studies have been carried out to underpin mechanistic insights.
