organic materials. Herein, we reported the synthesis and characterization of different selective 2-arylquinoline-based acyl hydrazones toward copper(I) salts. We explored the scope of the catalytic system based on copper/acyl hydrazones in the catalysis of C–N bond formation between N-heterocycles, specifically indoles, pyrroles and carbazoles, and aryl iodides as well as redox-A3 coupling of tetrahydroisoquinolines
促进铜催化的偶联反应的配体由于其增强铜的催化活性的能力而受到越来越多的关注,从而使这些反应适用于不同领域,例如药物,药学上感兴趣的分子和有机材料。在这里,我们报道了不同的基于选择性2-芳基喹啉的酰基对铜(I)盐的合成和表征。我们探索了基于铜/酰基的催化体系在N杂环(特别是吲哚,吡咯和咔唑与芳基碘化物)之间的C–N键形成催化以及四氢异喹啉的氧化还原A 3偶联反应中的作用范围。炔烃和醛。
