Polyaromatic ethers arene complexes

Fe-arene complexes have been employed for the same purposes as their Ru counterparts, namely, in the preparation of monomeric aryl ethers,463,486-488 polyaromatic ethers,489,490 and macrocyclic aryl ethers.491... 

Abd-El-Aziz and Bernardin have written an extensive review (314 references) describing the synthesis and reactivity of mono- and polyiron arene complexes.Examples of some polyiron complexes where polyaromatic ethers and thioethers are coordinated to pendant GpEe cationic moieties have been reported by Abd-El-Aziz and de Denus.i ""... 

Star-shaped polyaromatic ethers complexed with cyclopentadienyliron cations (92) have been prepared, in which the metallic moieties are evenly spaced throughout the length of the macromolecular branches (Scheme 24). By altering the nature of the aromatic spacers between the complexed arenes, it was possible to alter the properties of these materials. Electrochemical analysis of these polymers demonstrated that the iron centers underwent reversible reduction processes. For the hexa-metallic stars (n=l), two distinct redox couples were observed at , /2=-1.20 and-1.30 V...
