摘要

The efficient and stable catalyst applied to the transformation of amines into the corresponding imines and hydrogenation of nitroarenes under mild reaction conditions is reported. The catalytic performance of porous N-doped carbon with FeCu (FeCu@NPC) catalyst are tested by aromatic alcohol-based N-alkylated of amines with solvent-free and hydrogenation of nitroarenes via N2H4 center dot H2O. The results proved that the yield of these two reactions are all over 99.9% under optimum condition. Moreover, the synergistic effect of the catalyst for N-alkylated reaction was investigated through the kinetic study. The catalyst can be easily separated from reaction system by an external magnetism, and can be recycled and reutilized for at least 4 runs with conversions are all over 75%. The study of the catalyst indicated that it was suitable for the reactions in industry. Hence, the catalysis process by the inexpensive metals-based catalyst is green and sustainable.

Reductive N-Formylation of Nitroarenes Mediated by Rongalite

Huai-Yu Wang, Xiang-Long Chen, Chun-Yan Wu, Dong-Sheng Yang, Ting Chen, An-Xin Wu

Summary: Here, we present a straightforward method for the transition-metal-free reductive N-formylation of nitroarenes. This reaction utilizes the dual role of rongalite as a reductant and a C1 building block simultaneously. Our method provides an alternative approach for the synthesis of N-aryl formamides from nitroarenes, including the formation of a C-N bond. The utility of this protocol is demonstrated through scale-up synthesis and late-stage functionalizations of complex molecules.

Visible-light-induced iron-catalyzed synthesis of N-aryl amides from nitroarenes and chloroalkanes

Qun-Liang Zhang, Wenxin Liu, Yirong Zhou, Fang-Lin Zhang

Summary: An unprecedented reductive amidation reaction of chloroalkanes with nitroarenes was achieved by combining iron catalysis with visible-light photoredox catalysis. This environmentally benign protocol enabled the direct synthesis of diverse N-aryl amides using commercially inexpensive nitroarenes and chloroalkanes under mild conditions. This method offers advantages such as avoiding the use of external reductants and photocatalysts, simple manipulations, low cost, high step economy, and good functional group tolerance. Additionally, a preliminary investigation into the reaction mechanism revealed the isolation of a nitrone as a possible active intermediate, suggesting a successive two-step rearrangement in the catalytic cycle.

Ruirui Yun, Wei Zhang, Zan Zhang, Xiaoxuan Zhang, Zhaoxu Wang, Shizhong Luo

Summary: In this study, a series of core-shell catalysts Cu@NC/PC were designed and synthesized for the first time using a functional polymer assistant strategy. Cu@NC/PC-900-2 exhibited excellent catalytic performance in the hydrogenation of nitroarenes, attributed to its large BET surface area and uniformly dispersed metal sites. The honeycomb-like structure facilitated mass transfer and active site exposure. Both experimental and theoretical results indicated that the N-doping sites promoted the adsorption of nitro groups, resulting in high activity and selectivity under low H-2 pressure and temperature. Importantly, the catalyst also achieved high conversion in gram-scale catalytic processes, highlighting its practical application potential.

Summary: This study provides a comprehensive investigation into the catalytic condensation of renewable 3-carene with formaldehyde for the one-step preparation of terpenoid trans-4-hydroxymethyl-2-carene. Various acids and alumino-silicates were found to catalyze the reaction, but the selectivity to the desired product was limited. Phosphoric acid showed the highest selectivity, and an excess of formaldehyde or catalyst loading significantly increased the yield of the target product. Water presence also led to increased selectivity. Additionally, a detailed mechanism for the 3-carene condensation with formaldehyde was proposed and confirmed through kinetic modeling.
