Construction of N-substituted pyrrolidones from biomass-derived levulinicacid (LA) via reductive amination is a highly attractive route for biomass valorization. However, realizing this transformation using H2 as the hydrogen source under mild conditions is still very challenging. Herein, we designed porous TiO2 nanosheets-supported Pt nanoparticles (Pt/P-TiO2) as the heterogeneous catalyst. The prepared Pt/P-TiO2
通过还原胺化从生物质衍生的乙酰丙酸 (LA) 构建 N 取代的吡咯烷酮是一种极具吸引力的生物质价值化途径。然而,在温和条件下使用 H2 作为氢源实现这种转化仍然非常具有挑战性。在此,我们设计了多孔 TiO2 纳米片负载的 Pt 纳米粒子(Pt/P-TiO2)作为多相催化剂。制备的 Pt/P-TiO2 在环境温度和 H2 压力下对 LA 的还原胺化非常有效,以生产各种 N-取代的吡咯烷酮(34 个实例)。同时,Pt/P-TiO2对乙酰丙酸酯、4-乙酰丁酸、2-乙酰苯甲酸和2-羧基苯甲醛的还原胺化显示出良好的适用性。
