Abstract

Several known volatile <i>closo</i>-carboranes (1,5-C<sub>2</sub>B<sub>3</sub>H<sub>5</sub>, 1,6-C<sub>2</sub>B<sub>4</sub>H<sub>6</sub>, 2,4-C<sub>2</sub>B<sub>5</sub>H<sub>7</sub>, 1,10-C<sub>2</sub>B<sub>8</sub>H<sub>10</sub>) and their alkyl derivatives and ten new alkyl derivatives of these carboranes were identified from the thermal gas-phase flash reactions of B<sub>2</sub>H<sub>6</sub>, B<sub>3</sub>H<sub>7</sub>CO and B<sub>4</sub>H<sub>10</sub> with ethyne, propyne and but-2-yne. In addition, <i>nido</i>-C<sub>4</sub>B<sub>2</sub>H<sub>6</sub> and its methyl derivatives were obtained from B<sub>2</sub>H<sub>6</sub>-alkyne flash reactions. All carboranes found in these high-energy reactions are the most thermally stable isomers of their class. The non-isolable borane {B<sub>3</sub>H<sub>7</sub>} is suggested as the initiator in all thermal flash reactions reported here. <p>
