摘要 以2-吡啶甲酸为原料,经酯化、缩合、加成合成了平面四齿双核配体3,5-二(2-吡啶基)吡唑。改进合成方法使加成反应的产率由原来的66%提高到98%。 A planar tetradentate dinuclear ligand, 3,5-bis(2-pyridyl) pyrazole, was synthesized by a three-step reaction of esterification, condensation and addition. The yield of the addition reaction was increased from 66% to 98% because the synthesis method was improved.
