Allgemeine Beschreibung

Manganese(II) chloride tetrahydrate is the tetrahydrate form of manganese(II) chloride. It is used in the preparation of manganese-based hybrid compounds.

Anwendung

Manganese(II) chloride tetrahydrate can be used:      
  • As a promoter to synthesize dihydropyrimidin-2(1H)-ones by the condensation of aldehyde, β-dicarbonyl compounds, and urea under microwave conditions.      
  • As a catalyst to synthesize dihydro-2-oxypyrrole derivatives via one-pot four-component domino condensation of dialkyl acetylenedicarboxylate, formaldehyde, and amines.     
  • To synthesize active manganese oxide with potential application as an oxidant in organic synthesis.
