nitrogen compounds

• amides can be reduced to amines using LiAlH4 in dry ether, rtp
• nitrobenzene can be reduced to phenylamine using Sn (tin) catalyst, concentrated HCl and heat
• amine can react with anhydrous acyl chlorides to form amides at rtp in a nucleophilic acyl substitution reaction
• phenylamine can react with bromine (aq) to form 2,4,6-tribromophenylamine (s)
• amides can undergo:

  • acidic hydrolysis with HCl/H2SO4 (aq), heat, forming carboxylic acid and ammonium salt
  • alkaline hydrolysis with NaOH/KOH (aq), heat, forming carboxylate salt and ammonia/amine
