Chemistry – A European Journal, Volume 32, Issue 3, 16 January 2026.The design and synthesis of a linear tetradentate NCCN ligand incorporating two 1,2,3‐triazolin‐5‐ylidene mesoionic carbene donors, and its application to asymmetric iron catalysis is reported. This work represents the first example of an iron complex derived from a cis‐α‐coordinating tetradentate NCCN ligand, and notably, the first chiral iron ...
