Abstract

The treatment of salts of the B<sub>10</sub>H<sub>10</sub><sup>2-</sup> anion with the commercially available <i>N</i>-fluoro reagent 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (F-TEDA) resulted in the formation of fluorinated derivatives of this ten-vertex borane dianion. The effects of changing the solvent, temperature, and reagent stoichiometry were studied. The derivatives 1-B<sub>10</sub>H<sub>9</sub>F<sup>2-</sup>, 2-B<sub>10</sub>H<sub>9</sub>F<sup>2-</sup>, 1,2-B<sub>10</sub>H<sub>8</sub>F<sub>2</sub><sup>2-</sup>, 1,6-B<sub>10</sub>H<sub>8</sub>F<sub>2</sub><sup>2-</sup>, 1,10-B<sub>10</sub>H<sub>8</sub>F<sub>2</sub><sup>2-</sup>, and 1,2,10-B<sub>10</sub>H<sub>7</sub>F<sub>3</sub><sup>2-</sup> were examined by a combination of <sup>11</sup>B and <sup>19</sup>F NMR spectroscopy and by IR spectroscopy. The salt [Ph<sub>4</sub>P]<sub>2</sub>[1,10-B<sub>10</sub>H<sub>8</sub>F<sub>2</sub>] . 3 CH<sub>2</sub>C<sub>l2</sub> was structurally characterized by single-crystal X-ray crystallography: C<sub>51</sub>H<sub>48</sub>B<sub>10</sub>Cl<sub>6</sub>F<sub>2</sub>P<sub>2</sub>, monoclinic, <i>C2/c</i>, a = 13.8134(9), b = 19.141(1), c = 21.136(1) Å, β = 91.546(1)°, <i>Z</i> = 4, <i>T</i> = -100 °C, R = 0.077.
