Direct alkenylation of the C2‐position of indoles bearing an easily removable N‐pyrimidyl group with alkynes has been achieved by using a cobalt catalyst complexed with a phosphine–pyridine bidentate ligand. This reaction has wide substrate scope and is highly efficient and stereoselective at room temperature. The alkenylated indoles serve as useful platforms for further synthetic transformations (some

A general and efficient Rh(I)-catalyzed decarbonylativedirect C2-olefination of indoles with vinyl carboxylicacids has been developed. The reaction exhibits excellent functional group tolerance, regioselectivity and stereoselectivity, giving a broad range of C2-alkenylated indoles in good to excellent yields.
