A new synthetic route to unsymmetrically substituted benzophenones, relying upon iron-mediated reactions in all of the key steps, is described. The key buiding block, eta6-2-chloro-carbomethoxybenzene-eta5-cyclopentadienyl iron hexafluorophosphate (4), is reacted with a variety of substituted phenols, providing diarylether complexes (6). After hydrolysis of the ester functionalities, these complexes
