描述了2,5-二(2-吡啶基)噻唑并[5,4-d]噻唑(5)的第一金属配合物。报道了双核双(2,2'-联吡啶)钌络合物的游离配体5,双核铜络合物6和两个非对映异构体7meso和7rac的X射线晶体结构。两种7的非对映异构体和4,4'-二甲基-2,2'-联吡啶类似物8可以通过阳离子交换色谱法轻松分离。四种双核钌配合物的1 H NMR和可见光吸收光谱以及电化学数据表明,它们的HOMO-LUMO能隙相对较小,并且金属与金属之间的相互作用较弱。
多孔有机聚合物(POPs)近年来由于其高孔隙率,多样化的功能性和出色的化学稳定性而引起了分子吸附的广泛关注。在这项工作中,我们提供了系统的案例研究,涉及通过模型化合物形成噻唑并[5,4- d ]噻唑(TzTz)键并将其整合以合成一组三个新颖的,热化学稳定的TzTz键联的POP,即TzTz-POP-3 ,TzTz-POP-4 ,和TzTz-POP-5与分别三苯基苯,四苯基并四(羟基苯基)甲烷芯。有趣的是,代表的TzTz-POP-3的集成TzTz部分可以从水溶液中与副品红(FU)的混合物中化学选择性去除有机染料荧光素(FL)。所述TzTz-POP-3的≈1提供优异的化学选择性:7(FL:FU),相比于由于加上永久孔隙率和孔径适当窗口多个活性位点锚定的存在证实了类似的应用一样的多孔材料。

A microwave-assisted preparation of symmetrical thiazolo[5,4-d]thiazoles from the corresponding aldehydes is presented. The two-step reaction sequence comprises the condensation of aldehydes with dithiooxamide followed by oxidation/aromatization with 1,4-benzoquinone derivatives. The new procedure provides the desired products in good yields and in most cases allows reduction of the excess of aldehyde
介绍了一种微波辅助从相应的醛类制备对称的噻唑并[5,4- d ]噻唑的方法。两步反应序列包括醛与二硫代草酰胺的缩合,然后用1,4-苯醌衍生物的氧化/芳构化。与以前的方法相比,新方法以高收率提供了所需的产品,并且在大多数情况下,可以减少工艺中使用的过量醛。首次展示了该反应在芳族和脂族醛上的应用。

of disubstituted thiazolo[5,4-d]thiazoles was achieved by condensing two equivalents of an aryl aldehyde with dithiooxamide in nitrobenzene at 130 °C for 24 h. The method is tolerant to a range of aromatic aldehydes including derivatives of pyridine, quinoline, mono- and dihydroxybenzene. An X-ray crystal structure of 2,5-bis(2-hydroxy-3,5-di-tert-butylphenyl)thiazolo[5,4-d]thiazole was obtained confirming
