From oh to nh2
WebThe reduction of nitro compounds are chemical reactions of wide interest in organic chemistry. The conversion can be effected by many reagents. The nitro group was one of the first functional groups to be reduced. Alkyl and aryl nitro compounds behave differently. Most useful is the reduction of aryl nitro compounds. WebA carboxylic acid first adds to the DCC molecule to form a good leaving group, which can then be displaced by an amine during nucleophilic substitution to form the corresponding amide. The reaction steps are shown below: Step 1: Deprotonation of the acid. …
