this work, the use of Fe3O4/geraphene oxide nanocomposite as an efficient catalyst for the synthesis of 5-sulfanyltetrazole derivatives of indoles, pyrroles, and 5-alkyl sulfanyltetrazoles is described. These compounds are readily obtained by the reaction of the starting heterocycles indoles, N-aryl pyrroles, alkyl thiocyanates, and trimethylsilyl azide in good to excellent yields. Moreover, Fe3O4/GO
摘要 在这项工作中,描述了使用 Fe3O4/geraphene 纳米复合材料作为合成吲哚、吡咯和 5-烷基硫烷基四唑的 5-硫烷基四唑衍生物的有效催化剂。这些化合物很容易通过起始杂环吲哚、N-芳基吡咯、烷基硫氰酸酯和叠氮化三甲基甲硅烷以良好到极好的产率反应获得。此外,Fe3O4/GO 纳米复合材料可以很容易地通过外部永磁体从反应混合物中分离出来,并且可以连续重复使用至少六次,而不会显着降低产品的产率和催化活性。图形概要
