the cross-coupling of C–S bond is a highly attractive area of research due to the prevalence of aryl thioether in bioactive natural products, functional materials, agrochemicals, and pharmaceutically active compounds. Herein, we report a ligand-free Cu(I) mediated electrophilic thiolation of organostannanes with sulfur electrophiles. A selective transfer of alkyl groups was achieved in reactions with
由于芳基硫醚在生物活性天然产物,功能材料,农用化学品和药物活性化合物中的普遍存在,因此通过C–S键的交叉偶联合成芳基硫醚是一个非常有吸引力的研究领域。在这里,我们报道了有机锡与硫亲电体的无配体的Cu(I)介导的亲电硫醇化反应。在与烷基氨基甲酸酯反应得到拥挤的硫醚的反应中实现了烷基的选择性转移。这项研究提供了访问二芳基和芳基烷基硫醚的统一方法,并在后期修饰的背景下得到了证明。
