与迄今为止所接受的每种烯烃在其顺式和反式异构体之间进行相互异构化的概念相反，被蒽基和其它芳族多环基团取代的烯烃仅从其顺式异构体到反式异构体进行单向异构化，并且从其反式异构体到顺式异构体的反向异构化从未发生。探讨了烯烃异构化的反应机理及区分单向异构化和双向异构化的特征，以期对烯烃异构化反应有一个全面的认识。
Contrary to the hitherto accepted concept that every olefins undergo mutual isomerization between their cis-and trans-isomers, olefins substituted by anthracenyl and other aromatic polycyclic groups undergo only one-way isomerization from their cis-to trans-isomers, and the reverse isomerization from their trans-tocis-isomers never occurs. The mechanism for the one-way isomerization and the features to distinguish one-way or two-way isomerization is discussed to get whole view of the isomerization of olefins.
