A series of trans-dichloroiridium(IV)–salen complexes were synthesized and structurally characterized by spectroscopic means and X-ray crystal structures. These Ir(IV) complexes are able to catalyze intramolecular C–H amination of aryl azides. The catalytic amination was drastically accelerated under microwave-assisted conditions, and possibly involves Ir-imido intermediates as supported by high-resolution
