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):
MBrO
m
(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.
一种制备通式(3)所表示的芳香醛化合物的方法,包括将通式(1)所表示的苄基化合物(其中R可能代表氢原子,n表示1至6的整数,R'可以相同或不同,代表氢原子或具有取代基的烷基、苯基或烷基苯基)与通式(2)所表示的溴氧化物反应(其中M代表氢原子或金属原子,m表示1至3的整数),在酸催化剂的存在下进行。根据该方法,可以通过简单的操作,在不使用昂贵的催化剂或过渡金属的情况下高选择性地制备芳香醛化合物。
