摘　　要：以4,4′-二甲基-2,2′-联吡啶为原料,以单质碘和二甲亚砜混合体系,直接处理得到了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 treated with iodine and dimethylsulfoxide as oxidation system. The characterization of structure was confirmed by melt point and mass spectrometry, and the optimum conditions were obtained through the improvement.
