Application

Ammonium chloride can be used as a catalyst:
  • To synthesize 3,4-dihydropyrimidin-2-(1H)-ones via solvent-free Biginelli condensation reaction.
  • For the aldol condensation of carbonyl compounds.
  • In the thia-Michael addition reaction of thiols to different α-enones.
It can also be used as:
  • A promoter in the enantioselective hydrogenation of an unprotected β-enamine amides.
  • A pH-adjuster in the preparation of waterborne glucose silicone resin.
