Condensations of some ketones, such as cyclopentanone, cyclohexanone, indan-1,3-dione, 2-acetyl-1-naphthol, 1-acetyl-2-naphthol, with some active methylene compounds, such as malononitrile and cyanoacetate, in the presence of amine bases, diethylamine or triethylamine, were studied. The structures of the Knoevenagel condensation products were determined by spectral analyses.
在存在下,某些酮(如环戊酮,环己酮,茚满-1,3-二酮,2-乙酰基-1-萘酚,1-乙酰基-2-萘酚)与一些活性亚甲基化合物(如丙二腈和氰基乙酸酯)的缩合研究了胺碱,二乙胺或三乙胺的含量。Knoevenagel缩合产物的结构通过光谱分析确定。
