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.
- A promoter in the enantioselective hydrogenation of an unprotected β-enamine amides.
- A pH-adjuster in the preparation of waterborne glucose silicone resin.
