A process for producing an aromatic aldehyde compound represented by a general formula (3):
(wherein R' and n are as defined below), which comprises reacting a benzyl compound represented by a general formula (1):
(wherein R may represents hydrogen atom, n represents an integer of 1 to 6, and R' may be the same or different and represent a hydrogen atom or an alkyl gorup, an alkyl group or a phenyl group which may have a substituent) with an oxy-compound of bromine represented by the formula (2):
        MBrOm     (2)
(wherein M represents a hydrogen atom or a metal atom, and m represents an integer of 1 to 3) in the presence of an acid catalyst. According to this method, an aromatic aldehyde compound can be produced in high selectivity by a simple operation without using an expensive catalyst or transition metal.
                            一种生产通式(3)代表的芳香醛化合物的工艺:
(其中 R' 和 n 如下文所定义),该工艺包括使通式(1)所代表的苄基化合物发生反应:
(其中 R 可代表氢原子,n 代表 1 至 6 的整数,R'可相同或不同,并代表氢原子或烷基高尔基、烷基或可带有取代基的苯基)与通式(2)所代表的
溴的氧化合物反应:
MBrOm (2)
(其中 M 代表氢原子或
金属原子,m 代表 1 至 3 的整数)在酸催化剂存在下进行反应。根据该方法,无需使用昂贵的催化剂或过渡
金属,通过简单的操作即可生产出高选择性的芳香醛化合物。
