Abstract

Reduction of the tetrahedral complex (BIAN)FeCl₂ (6) (BIAN = 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene) in the presence of an arene, either as reaction solvent or in pentane solution affords a series of (BIAN)Fe(η⁶-arene) complexes (10–13). In the case of the sterically encumbered arene 2-methylnapthalene, 6 was converted to the (BIAN)Fe(COD) (14) (COD = 1,5-cyclooctadiene) complex first, before subsequent hydrogenation in the presence of 2-methylnaphthalene afforded the desired arene complex (15). The electronic structure of the arene complexes was interrogated, and the question of ligand redox non-innocence was addressed using X-ray diffraction studies as well as DFT and cyclic voltammetry.
