A thermoelectric conversion material containing an electrically conductive material (A) and an organic compound (B) that are in a relationship satisfying the following formula (1): 0 eV ≤ | (HOMO of the organic compound (B)) - (HOMO of the electrically conductive material (A)) | ≤ 1.64 eV.
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。
