Inorganic Chemistry

In this reduction reaction, the nitro group ( ) needs to be reduced to an amine group ( ) or similar. Sodium borohydride ( ) is a common reducing agent used for reducing nitro groups to amines or hydroxyl groups.
- is a mild and selective reducing agent that can reduce nitro groups to amines without affecting other functional groups like alcohols.
- Lithium aluminium hydride ( ) is a stronger reducing agent but is generally used for reducing esters, aldehydes, and ketones.
- (diborane) is typically used for the reduction of unsaturated compounds.
- Calcium oxide ( ) is not a reducing agent in this context.
Thus, the suitable reducing agent is .
