    • The invention relates to (1) a process for producing a cyanobenzaldehyde compound by converting the aminomethyl group in a cyanobenzylamine compound into an aldehyde group using an oxidizing agent without impairing the cyano group, to (2) a process for producing a cyanobenzoyl halide compound by converting the aldehyde group in a cyanobenzaldehyde compound into an acid halide group without impairing the cyano group, and to (3) a process for producing a cyanobenzoic acid compound by reacting a cyanobenzaldehyde compound with a hypohalogenous compound. According to the present invention, cyanophenyl derivatives that are useful as an intermediate of medical preparations, agricultural chemicals, liquid crystals, functional high molecular monomers and the like can be produced efficiently from raw materials that are obtained without difficulty.
    • 本发明涉及(1)通过使用氧化剂将氰基苄胺化合物中的氨基甲基转化为醛基而不损害氰基的方法,(2)通过以下方法制备氰基苯甲醛化合物的方法:(2)通过 将氰基苯甲醛化合物中的醛基转化成酰卤基团而不损害氰基,和(3)通过使氰基苯甲醛化合物与低级光化合物反应来制备氰基苯甲酸化合物的方法。根据本发明,氰基苯基衍生物 作为医药制剂,农药,液晶,功能性高分子单体等的中间体是有用的,可以从难以获得的原料中有效地制造。

    • The invention aims to provide a method whereby (meth)acrylate derivatives having an isocyanate group can be obtained in high yield by dehydrochlorination of 3-chloropropionate derivatives having an isocyanate group under industrially advantageous and mild conditions, and the content of residual hydrolyzable chlorine can be reduced. A method for producing a (meth)acrylate derivative having an isocyanate group comprises performing dehydrochlorination of a 3-chloropropionate derivative having an isocyanate group in the presence of a basic nitrogen compound having a tertiary nitrogen, the tertiary nitrogen of the basic nitrogen compound having at least one group other than an aromatic ring group.
