Abstract

A synthesis is described of the four <i>C</i>-halogenated 1-X-CB<sub>11</sub>H<sub>11</sub><sup>-</sup> anions (X = I, Br, Cl, F) using <i>N</i>-halosuccinimides and <i>N</i>-fluorobis(benzenesulfonyl)amine as halogenating agents. The procedure yields only the desired product next to unreacted starting material. Regularities in the <sup>11</sup>B and <sup>13</sup>C NMR chemical shifts of singly halogenated icosahedral carboranes are summarized. <p>
