Well-Defined Aryl-Fe^II Complexes in Cross-Coupling and C-H Activation Processes.

ABSTRACT: 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-Fe^II complexes [Fe^II(Br)(
