Non-iron [n]Metalloarenophanes

摘要

Tnhe past 15 years have witnessed the creation of a wealth ofnfascinating applications for strained [n]ferrocenophanes, in whichnthe aromatic sandwich rings of ferrocene are covalently tethered (nndenotes the number of bridging elements). By contrast, the relatedn[n]metalloarenophanes, that is, ansa-complexes not derived from fer-nrocene, have been neglected for a long time. In this Account, wenpresent the tremendous progress that has been achieved in thisnfield, mostly over the last five years. We focus on systems that havenbeen developed in our laboratories, namely, those based on [M(η6n-nC6H6)2] (where M is V, Cr, or Mo), [Mn(η5n-C5H5)(η6n-C6H6)], and [M(η5n-nC5H5)(η7n-C7H7)] (where M is V or Cr).
