詳細

アプリケーション

Ammonium chloride can be used as a catalyst:

• To synthesize 3,4-dihydropyrimidin-2-(1H)-ones via solvent-free Biginelli-condensation reaction[1].
• For the aldol condensation of carbonyl compounds[2].
• In the thia-Michael addition reaction of thiols to different α-enones[3].

It can also be used as:

• A promoter in the enantioselective hydrogenation of an unprotected β-enamine amides[4].
• A pH-adjuster in the preparation of waterborne glucose silicone resin[5].
