说明

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.
