Hypophosphites are reducing agents as they get oxidized to phosphonates as shown above. 82a Sodium hypophosphite was used as hydrogen source in water (containing 1% w/w Tween 20) for reduction of nitro compounds by Oba et al. 82b This process was catalyzed by Pd/C (10 mol%). Aromatic as well as aliphatic nitro compounds were reduced to amines at 50 °C in more than 99% yields. Sodium hypophosphite is also used for dehalogenation, debenzylation and double bond hydrogenation. Similarly, a mixture of phosphinic acid and sodium hypophosphite with Pd/C was used as a heterogeneous catalyst in a water:2-methyl-THF system by Popowycz and coworkers. 83 Here an aliphatic nitro group was selectively reduced in the presence of indole or coumarin. Nitroarenes were reduced to corresponding anilines in the presence of CN, ester, keto and halogen groups.

Again like NaBH 4-mediated reductions, the problem of work up, scaling up and use of excess reducing agent cannot be avoided for this system. However, the selectivity in the reduction process looks to be promising and further developments are expected. 4. Hydrazine hydrate Hydrazine hydrate is known to decompose in the presence of trace amounts of transition metal to hydrogen and benign N 2 gas. The in situ generation of hydrogen gas on an active metal surface thus facilitates the reduction process. Pd( II) phthalocyanine was also used with low catalyst loading up to 1 mol% along with NaBH 4 in EtOH by Verma et al. 38 Custom and animated emoji anywhere: Use any custom emoji from any servers you belong to, anywhere you can use emoji.Niestety zmiany na gorsze w polskim prawie praktycznie uniemożliwiają dalsze prowadzenie serwisu w obecnej formie w tym kraju.

Sm and AcOH in ionic liquid were used at r.t. for nitro reduction in inert atmosphere by Zheng and Zhang. 95 In this system halogen, CHO, COOH, CN, and NHTs groups were unaffected and corresponding anilines were obtained in 83 to 98% yields. CeY zeolite and formic acid under MW irradiation gave good yields of reduction products within 10 min. Aliphatic nitro compounds even with ester functionality were reduced to corresponding amines, while aldehyde, acid, amide, CN, Cl, Br were retained in corresponding anilines. 78

Tetramethyldisiloxane (TMDS)/Fe(acac) 3 was used for nitro reduction and the product amines were isolated as hydrochloride salts with good to excellent yields by Lemaire and coworkers. 59 Nitrile, acid, ester and bromo groups were well tolerated while p-nitrobenzaldehyde gave p-hydroxymethylaniline. m-Dinitrobenzene was selectively reduced to m-nitroaniline.
