Photocatalytic hydrogenation of nitrobenzenes to anilines over noble metal-free TiO2 utilizing methylamine as a hydrogen donor

Ultrafine Platinum Nanoparticles Derived from Supramolecular Crystal for Catalytic Hydrogenation of Nitroarenes

“…由于 苯胺类化合物的巨大作用, 开发廉价、高效的苯胺制备 方法依然是有机合成和化工工业中一个重要的研究方 向 [1][2][3][4][5][6][7][8] . 硝基苯直接催化加氢制备苯胺无疑是一种最为 直接、原子经济及环境友好的合成方法 [9][10][11][12][13][14][15][16][17] . 在催化加 氢反应中, 催化剂的催化活性对反应速率和产物质量具 有重要的影响.…”

Ag/Ag2O confined visible-light driven catalyst for highly efficient selective hydrogenation of nitroarenes in pure water medium at room temperature

“…To confirm the stoichiometry of this photocatalytic hydrogenation [39], we investigated the yields on the hydrogenation of nitrobenzene at different initial concentrations by HPLC. The aniline is obtained almost quantitatively towards the hydrogenation of nitrobenzene in pure water at room temperature (Figure S6), which is in good agreement with the standard curve of amine.…”

Rice husk-SiO2 supported bimetallic Fe–Ni nanoparticles: as a new, powerful magnetic nanocomposite for the aqueous reduction of nitro compounds to amines

“…This procedure was studied in different solvents such as EtOH, H 2 O, CH 2 Cl 2 , n-hexane, toluene and EtOAc and it was found that H 2 O is a suitable solvent for this reaction and with the nonpolar solvent under the same condition no reaction to proceeded (Table 2, entries 1-4). Then, the different reducing agents HCOOH, i PrOH and H 2 were studied (Table 2, entries [17][18][19]. These hydrogen sources showed lower activity compared to that of NaBH 4 .…”

“…14,15 Besides, nickel catalysis has made tremendous advances in organic synthesis, especially the synthesis of heterocycle compounds, which have been widely used among a variety of pharmaceutical compounds due to their relative insensitivity to air, low toxicity and price. [16][17][18][19][20] The design and preparation of green catalysts have attracted much attention in both academic area and pharmaceutical industry. 21 For this mean, heterogenization of the catalysts to solid supports is one of the interesting choices to prevent wasting the catalyst.…”
