Carbon–Carbon Bond Formation via Catalytically Generated Aminocarbene Complexes: Rhodium‐Catalyzed Hydroaminative Cyclization of Enynes with Secondary Amines
rhodium catalysts. The hydroaminative cyclization of 2‐vinylphenylacetylene derivatives with secondary amines gives 2‐aminoindenes in good yields. The reaction is considered to proceed through carbon–carbonbondformation on a catalytically generated aminocarbene ligand.
