Dichloromaleic acid diamides of the formula ##STR1## in which R represents an optionally substituted aliphatic radical with up to 8 carbon atoms, a cycloalkyl radical with 3 to 6 carbon atoms or a substituted phenyl radical, which possess fungicidal properties, are produced by reacting a dichloromaleic halide of the formula ##STR2## in which X is halogen, with an amine of the formula H.sub.2 N--R in a diluent and in the presence of an acid-binding agent.
公式为##STR1##的二氯马来酸二酰胺,其中R代表一个最多含有8个碳原子的可选择取代的脂肪基、一个含有3到6个碳原子的环烷基或一个取代苯基,具有杀真菌性能,通过在稀释剂中和存在酸中和剂的情况下,将公式为##STR2##的二氯马来酸卤与公式为H.sub.2 N--R的胺反应而制得。
