A variety of methods have been used in the synthesis of amino-substituted (η6-arene)(η5-cyclopentadienyl) iron(II) complexes. Conventional thermal ligand exchange of 2-fluoroaniline with ferrocene in the presence of Devarda’s alloy gave an Ullman

The 13C NMR chemical shifts (δ) for azaferrocenes, phosphaferrocenes and their precursor ligands have been used to determine coordination shifts, Δδ ( = δcomplex −δligand) for the complexes. For azaferrocenes, Δδ values were similar to that
