Abstract

On treatment of the [(1,2-C<sub>2</sub>B<sub>9</sub>H<sub>11</sub>)<sub>2</sub>Co]<sup>-</sup> ion with naphthalene in presence of AlCl<sub>3</sub> a remarkably bridged [8,8'-μ-(CH<sub>2</sub>-C<sub>9</sub>H<sub>6</sub>)-(1,2-C<sub>2</sub>B<sub>9</sub>H<sub>10</sub>)<sub>2</sub>-3-Co]<sup>-</sup> ion is obtained as a single isolated compound. The triatomic -CH<sub>2</sub>-C<sub>9</sub>H<sub>6</sub>- bridge is derived from the rearranged naphthalene nucleus. The mechanism of this reaction is obscure but it does resemble the "Electrophile-Induced Nucleophilic Substitution" reported earlier. The structure of the compound was established by multinuclear NMR spectroscopy and by single crystal X-ray diffraction.
