The thermal decomposition of sodium salt of (2,4,6-cycloheptatrien-1-yl)acetaldehydes tosylhydrazone (<B>4</B>, <B>6</B>, and <B>8</B>) afforded 9-substituted bicyclo[4.2.1]nona-2,4,7-triene (<B>9</B>, <B>11</B>, and <B>14</B>) and 9-substituted barbaralane (<B>10</B>, <B>12</B>, and <B>15</B>). In the case of <B>8</B>, products containing two nitrogen atoms (<B>17</B> and <B>18</B>) were isolated. The structure and the photochemical reaction of <B>17</B> provided strong support for the intermediacy of the tetracyclo[4.3.0.0<SUP>2,9</SUP>.0<SUP>5,7</SUP>]-nona-3-ene (<B>37</B>) derivative for the formation of the bicyclo[4.2.1]nona-2,4,7-triene derivatives. The difference in energy surface between C<SUB>9</SUB>H<SUB>10</SUB> and C<SUB>10</SUB>H<SUB>10</SUB> hydrocarbons was discussed.
