An Fe(III) catalyzed, efficient methodology for the synthesis of 2-aminobenzothiazole derivatives in water was established. This mild, base-free, one-pot strategy showcases the reaction of readily available 2-bromophenyl isothiocyanate with a broad range of substituted amines such as aliphatic, aromatic, primary, secondary and cyclic amines under air. Notably, the reaction afforded the corresponding
建立了一种 Fe(III) 催化的高效方法,用于在水中合成 2-氨基苯并噻唑衍生物。这种温和、无碱、一锅法的策略展示了现成的 2-溴苯基异硫氰酸酯与各种取代胺(如脂肪族胺、芳香族胺、伯胺、仲胺和环胺)在空气中的反应。值得注意的是,该反应在绿色条件下以中等至优异的收率提供了相应的产品。发现本优化对于脂肪族胺底物是非常理想的。此外,该催化剂可以成功回收和再循环至少 5 次,而不会降低效率。
