Facile exchange of naphthalene for η4-benzene in [Cr(η4-C6H6)(CO)3]2-

The η4-benzene in K2[Cr(Tη4-C6H6)(CO)3] (K22) exchanges with free naphthalene at room temperature to give [Cr(η4-C10H8)(CO)3]2- (52-), as established by oxidation to [Cr(η6-C10H8)(CO)3] (4), 1H NMR observation, and protonation to [Cr(η5-C10H9)(CO)3]- (6-). 1-Methylnaphthalene and 1,4-dimethylnaphthalene also exchange with 22~ if the corresponding naphthalenide is used as the reductant, and this leads to a single isomer of [Cr(η-C10H6Me2)(CO)3] (8) in which the Cr is bonded to the unsubstituted ring of the naphthalene.
