A direct C2–H thiolation of azoles with Bunte salts was achieved under the combined action of copper and silver salts, furnishing various substituted 2-thioazoles in moderate to good yields.
and mild carbon-sulfur coupling was realized by nickel catalysis under ball-milling conditions. The desired thioether products were generated from aryl iodides and aromatic thiol/disulfides with broad substrate scope. The Ni(i)/Ni(III) catalytic cycle was facilitated by the mechanochemistry process, thus providing an eco-friendly and time-saving strategy for the construction of the C−S bond in practical

difficult reactions and the synthesis of complexed molecules such as benzothiazole-sulfide aryls. In this work, CuI was successfully immobilized on the surface of magnetic Fe3O4 nanoparticles modified with aniline and 4-aminobenzoic acid [Fe3O4@ABA-Aniline-CuI nanocomposite] and its catalytic activity was investigated in the preparation of a broad range of benzothiazole-sulfide aryls and heteroaryls through

Research on the preparation of diallyl sulfides and selenides is always an important challenge among chemists because these compounds are of high biological, pharmaceutical, industrial and chemical importance. For this purpose, in this attractive and highly efficient approach, we wish to report that copper (I) chloride immobilized on magnetic nanoparticles modified with benzothiazole–pyrimidine ligand
二烯丙基硫醚和硒化物的制备研究始终是化学家面临的一个重要挑战,因为这些化合物具有很高的生物、制药、工业和化学重要性。为此,在这种有吸引力且高效的方法中,我们希望报告固定在用苯并噻唑-嘧啶配体(Fe 3 O 4 @BTH-Pyr-CuCl)修饰的磁性纳米粒子上的氯化铜(I)是一种新颖且有效的磁性纳米粒子。通过一类杂环化合物与芳基碘、硫和硒源反应形成 C-S 和 C-Se 键的可回收催化剂。通过FT-IR、SEM、TEM、EDX、元素图、TGA、XRD、VSM和ICP-OES技术很好地鉴定了Fe 3 O 4 @BTH-Pyr-CuCl纳米催化剂的结构。回收测试证实Fe 3 O 4 @BTH-Pyr-CuCl纳米催化剂重复使用6次,其活性没有明显降低。该方法几乎优于文献报道的杂环C-S和C-Se偶联的其他方法,原因如下,例如使用环境友好的溶剂、产品收率高、使用可以分离和重复使用以及在更短的时间内
