Aromatic Nitro

A study has been made of the reduction of substituted nitro compounds by magnesium in methyl alcohol. Some nitro compounds smoothly reduce to the corresponding azoxy compounds, while others yield a complex mixture of azo, azoxy, and other compounds. An investigation has been made of the various factors affecting the velocity of the reaction and the relative proportion of the products. An attempt is made to clarify the various reactions taking place.

Actived Carbon

The reduction of aromatic nitro compounds to corresponding azoxy compounds with sodium borohydride was catalyzed by BiO(OH)/actived carbon (AC), which was prepared by equivalent-volume impregnation. The influences of catalyst, sodium borohydride and sodium hydroxide amount were investigated with 10 mmol of nitrobenzene as substrate in methanol at room temperature. The suitable reaction conditions are as follows: 0.2 g of catalyst, 10 mmol of sodium borohydride and 0.1 g of sodium hydroxide. Under the conditions, the seven aromatic nitro compounds were reduced to corresponding azoxy compounds with 27%-90% yields. Moreover, slight deactivation was observed after nine cycles of the catalyst.

Aromatic Nitro

The electrochemical reduction of a series of water-insoluble aromatic nitro compounds with coulometrically generated chromium(II) has been investigated. Samples ranging from 0.2 to 0.5 μmol could be determined for several substances with a precision and accuracy of about 1%. The number of electrons involved in the reductions corresponded in most cases to the formation of hydroxylamines or amines, but in some instances to dihydrazo products.
