    • 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.
    • 一种制备由通式(3)表示的芳族醛化合物的方法:(其中R'和n如下所定义),其包括使通式(1)表示的苄基化合物:其中R可以表示氢 原子,n表示1〜6的整数,R'可以相同或不同,表示氢原子或烷基,可以具有取代基的烷基或苯基)与溴的氧化合物 由公式(2)表示:<?in-line-formula description =“In-line Formulas”end =“lead”?> MBrO (2)<?in-line-formula description (式中,M表示氢原子或金属原子,m表示1〜3的整数)在酸催化剂的存在下进行。 根据该方法,通过简单的操作可以高选择性地制备芳族醛化合物,而不使用昂贵的催化剂或过渡金属。
