green synthesis of 2,3-disubstitutedquinoxaline derivatives. These ionic liquids are in the solid state at room temperature and the synthesis is carried out via the one-pot condensation reaction of various o-phenylenediamine with 1,2-diketone derivatives. Benzoxazole and benzimidazole derivatives were also synthesized by these novel catalysts via the one-pot condensation from reaction orthoester with
在本文中,我们介绍了两种由丙烷磺酸盐官能化的有机阳离子和杂多阴离子组成的非常规离子液体化合物,作为绿色固体酸催化剂,可高效高效地绿色合成2,3-二取代喹喔啉衍生物。这些离子液体在室温下为固态,并且通过各种邻苯二胺与1,2-二酮衍生物的一锅缩合反应进行合成。这些新催化剂还通过原酸酯与邻氨基苯酚(苯并恶唑衍生物的合成)和邻苯二胺(苯并咪唑衍生物的合成)的一锅缩合反应合成了苯并恶唑和苯并咪唑的衍生物。所有实验均成功产生了所需的产物。
