Cycloaddition of 3-oxido-1-phenylpyridinium 8a to 1-cyanoacenaphthylene 9a affords three isomeric adducts (13, 14 and 15). Structures for these compounds resulted from a comparative NMR study, as well as an X-ray crystallographic determination of isomer 15. Attempts to eliminate HCN from compounds 13–15 resulted only in cycloreversion to 1-cyanoacenaphthylene.

The fluorescence of acenaphthylene follows a Stern-Volmer relationship in air-saturated ether giving a self-quenching constant KF=0.12M−1, indicating that the syn photodimer originates from the singlet state of acenaphthylene. By comparison, 1-cyanoacenaphthylene undergoes a more efficient self-quenching (KF= 2.8 M−1) in air-saturated ether. No excimer fluorescence was detected for 1-cyanoacenaphthylene
air乙烯的荧光在空气饱和的醚中遵循斯特恩-沃尔默(Stern-Volmer)关系,给出自猝灭常数K F=0.12M -1,表明合成光电二聚体起源于的单重态。相比之下,1-氰基ena烯经历了更有效的自猝灭(K F = 2.8 M -1)在空气饱和的乙醚中。溶液中1-氰基o烯和母体化合物均未检测到准分子荧光。通过敏化或由重原子溶剂(EtI)诱导而获得的1-氰基ph乙烯的三重态显示出以高化学产率独家生成了头对头抗光二聚体。在该反应中观察到的区域专一性和立体专一性表明indicates烯环和氰基在稳定双自由基过渡态中的影响。

The influence of several parameters (concentration, quencher, solvent heavy atom effect, ionic detergents, heavy atom effect of counter ions) on the isomer distribution is studied for the photodimerization of acenaphthylene and some 1-derivatives.
