摘要
以Al Cl3为催化剂,三苯氨(1)和原甲酸三乙酯(2)为原料,合成了4-(二苯氨基)苯甲醛(3),其结构经1H NMR和FT-IR确证。合成3的较佳工艺条件为:1 40 mmol,n(1)∶n(2)∶n(Al Cl3)=1∶5∶8,苯为溶剂,于30℃反应4 h,收率91%。
4-(Diphenylamino) benzaldehyde (3) was synthesized by the reaction of triphenylamine (1) with triethyl orthoformate (2) using aluminium trichloride as the catalyst. The structure was con- firmed by 1H NMR and FT-IR. The optimum reaction conditions of synthesizing 3 at 30 ℃ for 4 h were as follows: 1 was 40 retool, n(1) :n(2) :n(A1CI3) = 1:5:8, benzene was solvent. The yield was 91% under the optimum reaction conditions.
