N-Formylanilido aromatic compounds containing at least two electron-withdrawing substituents in the benzene ring are obtained by reacting together equimolecular quantities of a formanilide and an aromatic halogen compound in the presence of a diluent and an acid-binding agent at a reaction temperature below that which causes decarbonylation. The corresponding anilido aromatic compounds are obtained by conducting the process at a reaction temperature above the temperature of decarbonylation or by heating the N-formylanilido aromatic compounds above their temperature of decarbonylation.
在稀释剂和酸结合剂的存在下,等分子量的甲酰
苯胺和芳香族卤素化合物在低于脱羰基化温度的反应温度下发生反应,可得到苯环上至少含有两个抽电子取代基的 N-甲酰
苯胺基芳香族化合物。 在高于脱羰基化温度的反应温度下进行该过程,或将 N-甲酰
苯胺基芳香族化合物加热至高于其脱羰基化温度,可得到相应的
苯胺基芳香族化合物。
