以4,4’-二甲基-2,2’-联吡啶为原料,以二氧化锰-硫酸和三氧化二锰-硫酸体系作为氧化剂,直接氧化得到了2,2’-联吡啶-4,4’-二甲醛,通过熔点和质谱对产物结构进行了表征,并进一步优化,得到最佳工艺条件.%2,2'-bipyridine-4,4'-dicarbaldehyde was synthesized from 4,4'-dimethyl-2,2'-bipyridine by direct oxidation using MnO2-H2SO4 or Mn2O3-H2SO4 as oxidation system. The characterization of structure was confirmed by melt point and mass spectrometry,and the optimum conditions obtained through the further optimization.
