Beschreibung

Anwendung

Manganese(II) chloride tetrahydrate may be used to accelerate the synthesis of dihydropyrimidin-2(1H)-ones by the condensation of aldehyde, β-dicarbonyl compounds and urea under microwave conditions. It may also be used in the synthesis of manganese(II) tris(2-benzimidazolylmethyl)amine (ntb) complexes.
