A mild, facile, and efficient synthesis of fluorescent naphthalimide dyes via CuI-catalyzed CN, CO, and CS Ullman-type condensation reactions using amines, alcohols, and thiols is described. The reactions were carried out in the presence of KF/Al2O3 as a mild basic support in water as a green solvent. This protocol tolerates a wide range of functional groups and provides functionalized naphthalimide
描述了一种温和,简便,有效的合成方法,该方法通过使用胺,醇和硫醇的CuI催化的C N,C O和C S Ullman型缩合反应合成荧光萘二甲酰亚胺染料。反应在作为绿色溶剂的水中作为温和碱性载体的KF / Al 2 O 3的存在下进行。该方案可耐受各种官能团,并能以良好至极佳的产率提供官能化的萘二甲酰亚胺染料。
