制备方法与用途

应用

由于3-溴-2-吡啶羧酸有机配体具有优异的配位能力，在研究这类双功能配体与金属自组装形成的配合物时已有报道。科研工作者通过前期结构设计，不仅在调控3-溴-2-吡啶羧酸类配体和配合物结构的同时实现了对配合物性能的调控，还通过结构修饰引入不同电子效应的取代基对配合物的骨架结构与性质产生了重要影响。因此，在设计构筑金属有机框架（MOFs）时需要考虑自组装过程中的电荷补偿问题。目前，由3-溴-2-吡啶羧酸配体构建的配合物广泛应用于荧光传感、气体吸附/分离、磁性以及催化等领域。

制备工艺

汞吡啶-2,3-二羧酸盐在热Me2SO或HMPA中脱羧，得到I（主要产物）和II。I与Cl-或I-反应生成混合物；R = Cl, iodo; R1 = H)。三溴离子I和II (RR1 =键)得到I、II (R = Br, R1 = H)，然后碘离子在热HOAc中，I和II (RR1 =键)得到双(羧基吡啶基)汞III (X = H+HgI3-)。溶液在Me2SO沉积的III (X = 电子对)。吡啶-2,3-二羧酸根离子与Hg(OAc) 2在pH为5.0至5.8的煮沸aq. HOAc溶液中反应，得到MeCO2HgCH2CO2H作为唯一的金属有机产物，并通过硅胶柱层析纯化得到3-溴-2-吡啶羧酸。
