A method for producing an aldehyde, which comprises reacting an olefinic compound with carbon monoxide and hydrogen in the presence of a Group VIII metal compound and an organic phosphite compound to produce a corresponding aldehyde, wherein an organic phosphite compound of the formula (I):
wherein each of R1 and R2 which may be the same or different, is a 2-naphthyl group which may have a substituent, provided that at least one of R1 and R2 is a substituted 2-naphthyl group of the formula (II):
wherein R4 is a C1-30 organic group, and each of Rs, R6, R7, R8 and R9 which may be the same or different, is a hydrogen atom or an organic group, and R3 is ① a 2-naphthyl group which may have a substituent, ② a phenyl group which may have a substituent, or ③ an alkyl group which may have a substituent, is used as said organic phosphite compound.
一种生产醛的方法,包括在第八族金属化合物和有机亚磷酸酯化合物存在下,使烯烃化合物与一氧化碳和氢反应生成相应的醛,其中有机亚磷酸酯化合物为式(I):
其中 R1 和 R2 可相同或不同,各自为可具有取代基的 2-萘基,条件是 R1 和 R2 中至少有一个是式(II)的取代 2-萘基:
其中 R4 是 C1-30 有机基团,Rs、R6、R7、R8 和 R9 中的每一个可以相同或不同,是氢原子或有机基团,R3 是①一个可以有取代基的 2-萘基,②一个可以有取代基的苯基,或③一个可以有取代基的烷基。
