Well‐Defined [CpCo(N,O)I]‐Catalysts for Site‐Selective Intramolecular C−H Amidation
We present an efficient method for forming C−N bonds via intramolecular amidation catalyzed by well‐defined Cp*Co(N,O)I complexes. The reaction has been operate under mild conditions and produced a regioselective amidation product without the use of a bulky counter anion or expensive fluorinated sol...

| description | We present an efficient method for forming C−N bonds via intramolecular amidation catalyzed by well‐defined Cp*Co(N,O)I complexes. The reaction has been operate under mild conditions and produced a regioselective amidation product without the use of a bulky counter anion or expensive fluorinated solvents. The Cp*Co(N,O)‐I catalyst is very effective for intramolecular benzylic, tertiary, and internal C(sp3)−H bond amidation, but ineffective for intramolecular C(sp2)−H bond amidation. |
