Continuous hydrogenation of nitrobenzene to aniline was developed by Poliakoff and coworkers in high-temperature pressurized water (HTPW) using H 2 generated by thermal decomposition of HCOOH. 77 This reaction is carried out in the absence of any added catalyst and can be conveniently performed on a laboratory scale. Longer Messages: Say how you really feel with an increased character count limit of 4000 characters. Alternatively, the reduction of aromatic nitro compounds to the corresponding amines with silanes catalyzed by high-valent oxo-rhenium complexes is reported by Fernandes and coworkers. 58a The catalytic systems PhMe 2SiH/ReIO 2(PPh 3) 2 (5 mol%) and PhMe 2SiH/ReOCl 3(PPh 3) 2 (5 mol%) reduced efficiently a series of aromatic nitro compounds in the presence of a wide range of functional groups such as ester, halogen, amide, sulfone, lactone, and benzyl. This methodology also allowed the regioselective reduction of dinitrobenzenes to the corresponding nitroanilines and the reduction of an aromatic nitro group in the presence of an aliphatic nitro group. Similarly, Wilkinson's catalyst, RhCl(PPh 3) 3, was also used along with Et 3SiH in refluxing toluene for reduction of nitroarenes. 58bProfile Upgrades: add an animated avatar, a banner image, and a profile theme to personalize how you present yourself. Reduction was achieved in refluxing MeOH–water mixture using FeS and ammonium chloride by Desai et al. 87 Sensitive substituents like chloro, ester, and N-benzyl were unreactive in this reduction and corresponding anilines were obtained in 56 to 81% yields. Te metal was used as a reducing agent for preparation of anilines from nitroaromatics in neat critical water at 275 °C by Wang et al. 88 Electron-donating (Me) and electron-withdrawing (MeCO, Cl) substituents were well tolerated. However, in the case of Br and I derivatives, competitive dehalogenation takes place. Carboxylic acid group also undergoes decarboxylation. This process does not reduce aliphatic nitro and nitrostyrenes. The discussion is organized with respect to the use of reducing agents such as molecular H 2, hydrides, hydrazine, in situ H 2 generation, metal reductants, redox systems, light-induced electron transfer and biotic reduction in benign, clean, non-hazardous and non-polluting processes for reduction of nitroarenes. b) C.
