The condensation of organozinc compounds with nitriles gives either β-ketonitriles or ketenaminonitriles , according to the method used. When the starting nitrile is aromatic, and also in the case of α-bromoisobutyronitrile a nitrogen compound was observed similar to a β-lactimine nitrile.

The ultravioletabsorptionspectra of the low and high melting forms of β-aminocrotononitrile (I) provide evidence that both of them possess the same enamine structure. Since the existence of the polymorphic modifications of I must be excluded on the basis of the thermochemical behavior of I, the difference of the two modifications is capable of accounting for cis and trans isomerism, the low melting
β-氨基巴豆腈 (I) 的低熔点和高熔点形式的紫外吸收光谱提供证据表明它们都具有相同的烯胺结构。由于必须根据 I 的热化学行为排除 I 的多晶型修饰的存在,因此两种修饰的差异能够解释顺式和反式异构现象,低熔点修饰为顺式,高熔点修饰为顺式。熔融改性是反式形式。在 I 与芳香格氏试剂的反应中,CH3-CO-CH==C(NH2)-R 类型的 β-氨基酮作为主要反应产物形成。 I 的形成是假设的。
