    • PURPOSE: A producing method of a binaphthol aldehyde derivative is provided to increase the selectivity for a hydrogen position of a 2,2'-binaphthol-3-aldehyde 2` hydroxy group, and to produce the binaphthol aldehyde derivative without generating by-products. CONSTITUTION: A producing method of a binaphthol aldehyde derivative marked as chemical formula 1 comprises the following steps: reducing a compound marked as chemical formula 3 to obtain a compound marked as chemical formula 2; and oxidizing the compound marked as the chemical formula 2. In the chemical formula 1~3, X is selected from the group consisting of hydrogen, halogen, amino, nitro, cyano, formyl, carboxyl, substituted or non-substituted alkyl of C1~C10, alkylcarbonyl of C1~C10, aryl of C6~C10, and alkoxy of C1~C10. N and M are integers of 0~5.

    • PURPOSE: A method for manufacturing benzaldehyde or benzyl ketone is provided to prepare benzaldehyde or benzyl ketone at a high yield using environment-friendly urea-hydrogen peroxide and a reaction instead of conventional toxic organic solvent and oxidizer. CONSTITUTION: A method for manufacturing benzaldehyde or benzyl ketone comprises a step for oxidizing a first benzyl alcohol or a second benzyl alcohol with urea-hydrogen peroxide catalytically using magnesium bromide (MgBr2) under an ionic liquid. The first benzyl alcohol is selected from PhCH2OH, p-CH3C6H4CH2OH, p-FC6H4CH2OH, p-ClC6H4CH2OH, p-BrC6H4CH2OH, p-H3COC6H4CH2OH, p-NO2C6H4CH2OH, p-CF3C6H4CH2OH, 1-naphthalenemethanol, p-HOC6H4CH2OH, and p-CNC6H4CH2OH.
    • 目的:提供苯甲醛或苄基酮的制备方法,以环保型脲 - 过氧化氢和反应代替常规的有机有机溶剂和氧化剂,以高产率制备苯甲醛或苄基酮。 构成:用于制备苯甲醛或苄基酮的方法包括在离子液体下使用溴化镁(MgBr 2)催化地用脲 - 过氧化氢氧化第一苄醇或第二苄醇的步骤。 第一苄醇选自PhCH2OH,p-CH3C6H4CH2OH,p-FC6H4CH2OH,p-ClC6H4CH2OH,p-BrC6H4CH2OH,p-H3COC6H4CH2OH,p-NO2C6H4CH2OH,p-CF3C6H4CH2OH,1-萘甲醇,对HOC6H4CH2OH和p-CNC6H4CH2OH。
