A process for producing an unsaturated dicarboxylic acid imide compound of formula (I):
wherein D represents a divalent organic group having at least one carbon/carbon double bond; R¹ represents an n-valent organic group having at least one carbon atom; and n is an integer of 1 or above, which comprises reacting an unsaturated amide acid compound of formula (II):
wherein D, R¹, and n are as defined above, with an orthoester of formula (III):
R²-C⁅OR³]₃ (III)
wherein R² and R³, which may be the same or different, each represents a monovalent organic group having at least one carbon atom, to form an unsaturated dicarboxylic acid amide acid ester compound of formula (IV):
wherein D, R¹, R³, and n are as defined above, and then imidating the compound of formula (IV).
一种制备式(I)的不饱和二羧酸酰亚胺化合物的方法:其中D表示至少具有一个碳/碳双键的二价有机基团;R¹表示至少具有一个碳原子的n价有机基团;n为1或以上的整数;包括将式(II)的不饱和酰胺酸化合物与式(III)的正酯发生反应:R²-C⁅OR³]₃ (III),其中R²和R³,可以相同也可以不同,每个都表示至少具有一个碳原子的一价有机基团,形成式(IV)的不饱和二羧酸酰胺酸酯化合物:其中D,R¹,R³和n如上定义,然后对式(IV)的化合物进行亚胺化。
