investigated with aromatic hydrocarbons of petroleum naphtha using two biopolymer supported MnO2 nanostructured catalysts, MnO2@cellulose–SO3H and MnO2@wool–SO3H, for the synthesis of α-amino amides, 3,4-dihydroquinoxalin-2-amine, 4H-benzo[b][1,4]thiazin-2-amine, and cyanophenylamino-acetamide derivatives. Nano-MnO2@cellulose–SO3H and nano-MnO2@wool–SO3H were used as biodegradable oxidation and solid acid
一种新颖的多米诺氧化芳族烃(OU-3CR)的卯木型三组分反应已经研究了使用两个生物聚合物石脑油的芳族烃的MnO支持的2纳米结构的催化剂,的MnO 2 @纤维素-SO 3 H和的MnO 2 @wool -SO 3 H,用于合成α-氨基酰胺,3,4-二氢喹喔啉-2-胺,4 H-苯并[ b ] [1,4]噻嗪-2-胺和氰基苯基氨基乙酰胺衍生物。纳米的MnO 2 @纤维素-SO 3 H和纳米的MnO 2 @羊毛-SO 3H被用作可生物降解的氧化和固体酸催化剂。分别使用MnO 2 @纤维素-SO 3 H和MnO 2 @羊毛-SO 3 H可获得最佳的氧化和缩合工艺结果。据我们所知,该方法可被视为具有纳米MnO 2催化剂的烷基芳烃OU-3CR的第一个实例,从实践的角度来看,这将是非常有用的。
