Abstract

Syntheses and structures of [8,8'-μ-(OSO<sub>2</sub>O)(1,2-C<sub>2</sub>B<sub>9</sub>H<sub>10</sub>)<sub>2</sub>-3-Co]<sup>-</sup>and [(8-Ph-1,2-C<sub>2</sub>B<sub>9</sub>H<sub>10</sub>)-3-Co-(1',2'-C<sub>2</sub>B<sub>9</sub>H<sub>11</sub>]<sup>-</sup> ions and of [(8-dioxane-1,2-C<sub>2</sub>B<sub>9</sub>H<sub>10</sub>)-3-Co-(1',2'-C<sub>2</sub>B<sub>9</sub>H<sub>11</sub>)] zwitterion are described. All compounds result on dimethyl sulfate induced nucleophilic B-substitution of the parent cobalta-carborane sandwich ion under acid catalysis. A general mechanism is proposed. Constitutions of all compounds are inferred from the mass and multinuclear NMR spectroscopy and all structures are established by X-ray diffraction. Selected NMR and X-ray data are presented.
