hydrogenation of N-substituted imides and polyimide to generate primary amines, diols, and lactones. Catalyzed by Ag/TiO2, this reaction proceeded smoothly in high yields and selectivities for N-alkyl and N-aryl phthalimides and N-aryl succinimides, which also had activity for the degradation of waste polyimide plastics. In contrast to the typical Gabriel process, this reaction does not need any toxic reagent
我们报告了 N-取代酰亚胺和聚酰亚胺的首次非均相催化氢化生成伯胺、二醇和内酯。在Ag/TiO 2催化下,该反应以高产率和高选择性顺利进行,生成N-烷基和N-芳基邻苯二甲酰亚胺和N-芳基琥珀酰亚胺,对废聚酰亚胺塑料也具有降解活性。与典型的加布里埃尔过程相比,该反应不需要任何有毒试剂,而且副产物也非常有用。回收实验表明催化剂Ag/TiO 2可以很容易地回收而不降低催化活性。
