- 論文の詳細を見る
Flash vacuum pyrolysis of the title diazo compound gives 4<I>H</I>-cyclopenta[<I>def</I>]phenanthrene, which is interpreted as indicating that dibenzo[<I>ad</I>]cycloheptatrienylidene (<B>13</B>) undergoes the carbene–carbene rearrangement to generate 4-phenanthrylcarbene. The reactivities of <B>13</B> are compared with those of other benzoannulated cycloheptatrienylidenes and discussed in terms of the effect of the benzo ring to the activation energy for the rearrangement.
