将固态的2-（3，4，5-三甲氧基苯基）-4-（3，4-亚甲二氧基苯基）-4-氧代-2-丁烯腈（β-氰基查耳酮）的（E）-异构体（4 E）暴露于阳光下，通过异构化导致不寻常的二聚反应，得到不对称的E-Z二聚体（7），沿着由光反应性（Z）-异构体（4 Z-b）得到的对称的Z-Z二聚体（5）。
Exposure of the (E)-isomer (4E) of 2-(3, 4, 5-trimethoxyphenyl)-4-(3, 4-methylenedioxyphenyl)-4-oxo-2-butenonitrile (β-cyanochalcone) in the solid state to sunlight led to unusual dimerization through isomerization to give an unsymmetrical E-Z dimer (7) along with a symmetrical Z-Z dimer (5) obtainable from the photoreactive (Z)-isomer (4Z-b).
