Herein we explore the intrinsic organometallic reactivity of iron embedded in a tetradentate N3C macrocyclic ligand scaffold that allows the stabilization of aryl-Fe species, which are key intermediates in Fe-catalyzed cross-coupling and C-H functionalization processes. This study covers C-H activation reactions using Me L H and FeCl2, biaryl C-C coupling product formation through reaction with Grignard reagents, and cross-coupling reactions using Me L Br or H L Br in combination with Fe0(CO)5. Synthesis under light irradiation and moderate heating (50 °C) affords the aryl-FeII complexes [FeII(Br)( Me L)(CO)] (1 Me ) and [FeII( H L)(CO)2]Br (1 H ). Exhaustive spectroscopic characterization of these rare low-spin diamagnetic species, including their crystal structures, allowed the investigation of their intrinsic reactivity
