Bis(1,2,3,4-eta~4-anthracene)ferrate(l-):A Paramagnetic Homoleptic Polyarene Transition-Metal Anion

摘要

Homoleptic naphthalene and anthracene metal complexes of the d-block elements are exciting candidates for"naked"metal atom reagents owing to the unusual lability of these coordinated polycyclic aromatic hydrocarbons(or poly-arenes)in ligand-substitution reactions.Although cationic and neutral homoleptic polyarene metal complexes have been established for over 25 years,the first well-defined anionic version,tris(eta~4-naphthalene)zirconate(2-),was only reported in 1994.
