Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The treatment of an antiaromatic norcorrole Ni^II complex with a kinetically stabilized silylene provided ring‐expansion products in excellent yields through the highly regio‐ and stereoselective insertion into the β‐β pyrrolic CC bonds. The resultant Ni^II porphyrinoid monoinsertion product exhibited relatively strong near‐IR absorption bands due to the small HOMO–LUMO gap in spite of the disrupted cyclic π‐conjugation by the silicon atom.</p> </abstract>
