Prochiral aminoketones are key intermediates for the synthesis of optically active amino alcohols, and glycerol is one of the main biomass‐based alcohols available in industry. In this work, glycerol was catalytically activated and purposefully converted with amines to generate highly valuable prochiral aminoketones, as well as N‐formamides and N‐methyl amines, over CuNiAlOx catalyst. The catalyst structure

N-methylated compounds over different catalysts. Herein, we report the selective synthesis of formamides, 1,2-bis(N-heterocyclic)ethanes, and methylamines, which is achieved over an ionicliquid (IL, e.g., 1-butyl-3-methylimidazoliumtetrafluoroborate, [BMIm][BF4])-Pd/C catalytic system. By simply varying the reaction temperature, formamides and methylamines can be selectively produced, respectively

A range of 1,2-vicinal diamines were smoothly converted into N,N-dialkylformamides under the synergistic actions of Ru(bpy)3Cl2 photo-catalyst, 45 W household lighting bulb, and Cs2CO3 basic additive under very mild reaction conditions. The process involves visible light-enabled photo-catalytic cleavage of C–C bond as the strategic event.
在非常温和的条件下,Ru(bpy)3 Cl 2光催化剂,45 W家用电灯泡和Cs 2 CO 3碱性添加剂的协同作用下,将一系列1,2-邻位二胺顺利转化为N,N-二烷基甲酰胺反应条件。该过程涉及可见光激活的C–C键的光催化裂解,这是战略性事件。
