The coupling of bis(xylylisocyanide) complex of Pd(II) with 1,2,4-thiadiazole-5-amines leads to the formation of an equilibrium mixture of the binuclear complexes. In each of the studied cases, one of the formed complexes is the kinetic product, and the other one is the thermodynamic product. The complexes which are thermodynamic products have been isolated in the pure form and characterized by means
Pd(II)的双(二甲苯基异氰化物)配合物与1,2,4-噻二唑-5-胺的偶联导致双核配合物平衡混合物的形成。在每种研究的情况下,形成的络合物之一是动力学产物,另一种是热力学产物。作为热力学产物的配合物已经以纯净的形式分离出来,并通过高分辨率质谱,IR和NMR光谱以及X射线衍射分析进行了表征。溶液中区域异构化的NMR研究表明,与动力学产物相比,热力学产物的相对稳定性高于相应的包含1,3-噻唑或1,3,4-噻二唑片段的区域异构体。
