The preparation of the geometrical isomers of ethyl α-nitrocinnamate and α-nitrochalcone is described. Ethyl (E)-α-nitrocinnamate and (Z)-α-nitrochalcone were obtained by the thermal- or photoisomerization of the corresponding geometrical isomers, which were themselves produced predominantly through the Knoevenagel reaction. The facile addition of ethanol to the double bonds of β,β-dinitrostyrene,
描述了α-硝基肉桂酸乙酯和α-硝基查尔酮几何异构体的制备。(E)-α-硝基肉桂酸乙酯和 (Z)-α-硝基查尔酮是通过相应几何异构体的热异构化或光异构化获得的,它们本身主要通过 Knoevenagel 反应产生。还描述了在室温下在没有任何催化剂的情况下将乙醇轻松添加到 β,β-二硝基苯乙烯、α-硝基肉桂酸乙酯和 α-硝基查耳酮的双键上。
