碘 二甲亚砜 2 2′-联吡啶-4 4′-二甲醛 制备
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.
