AbstractOxidative C‐2 olefination of indoles/pyrrole via rhodium(III)‐catalyzed direct CH bond activation is reported. Phenolic OH and aniline NH2 units were revealed to be effective chelating groups to activate the aryl CH bond. The reactions proceeded with excellent selectivity and high functional group tolerance, furnishing 2‐vinylindoles/2‐vinylpyrroles in good yields.magnified image
