A facile reductive carbonylation reaction of nitroarenes to N‐arylformamide synthesis was investigated under polymer supported palladium (Pd@PS) nanoparticles catalyzed conditions. Dual role of oxalic acid dihydrate ((CO₂H)₂ ⋅ 2H₂O) as H₂ source for hydrogenation and CO source for carbonylation reaction for desired products synthesis was critically investigated under favorable DMF solvent conditions. Several cross experiments were performed to establish the best possible hypothesis for the proposed mechanism and understanding about the involvement of CO in the reaction pathway. Further, ortho‐substituted nitroarenes were found to be highly specific for facile para‐hydroxylation to give corresponding para‐hydroxy N‐aryl formamides.

负载钯纳米颗粒催化硝基芳烃还原羰基化为N-芳基甲酰胺

在聚合物负载的钯（Pd @ PS）纳米颗粒催化条件下，研究了硝基芳烃对N-芳基甲酰胺合成的简易还原羰基化反应。草酸二水合物的双重作用（（CO ₂ 2H）₂ ⋅2H ₂ O）以H ₂源用于氢化和羰基化反应的CO源为所需产物的合成有利DMF溶剂的条件下严重的影响。进行了几次交叉实验，以为提出的机制建立最佳假设，并了解CO在反应路径中的参与。此外，还发现邻位取代的硝基芳烃对简便的对位具有高度特异性-羟基化生成相应的对羟基N-芳基甲酰胺。
