作为由一个碳原子和两个稳定的中性离去基团组成的化合物的一个实例，合成了7-异氰基-7-氮杂二苯并降冰片二烯，CN（2）A（1，A = C14 H10或蒽），并进行了光谱和结构表征。1的末端C原子可以转移：异亚丙基腈氧化物与1反应生成一氧化碳，可能是通过N-异氰酸酯OCN（2）A的中间体。1与[RuCl_2（CO）（PCy_3）（2）]反应生成[RuCl_2（CO）（1）（PCy_3）（2）]，其非选择性分解：在产物混合物中，检测到碳化物络合物[RuCl_2（C）（PCy_3）（2）]。在固态或溶液中加热时，1分解为A、N-2和氰（C2 N2），如使用分子束质谱、IR和NMR光谱技术证实的。
Targeted as an example of a compound composed of a carbon atom together with two stable neutral leaving groups, 7-isocyano7- azadibenzonorbornadiene, CN(2)A (1, A = C14H10 or anthracene) has been synthesized and spectroscopically and structurally characterized. The terminal C atom of 1 can be transferred: mesityl nitrile oxide reacts with 1 to produce carbon monoxide, likely via intermediacy of the N-isocyanate OCN(2)A. Reaction of 1 with [RuCl2(CO)(PCy3)(2)] leads to [RuCl2(CO)(1)(PCy3)(2)] which decomposes unselectively: in the product mixture, the carbide complex [RuCl2(C)(PCy3)(2)] was detected. Upon heating in the solid state or in solution, 1 decomposes to A, N-2 and cyanogen (C2N2) as substantiated using molecular beam mass spectrometry, IR and NMR spectroscopy techniques.
