    DESCRIPTION

    General description

    Magnesium sulfate heptahydrate is a hydrated salt of magnesium. It is commonly used as a catalyst in organic synthesis.

    Application

    Magnesium sulfate heptahydrate can be used as a Lewis acid catalyst to synthesize:
    • Phenazine and quinoxaline derivatives via a condensation reaction between o-phenylenediamines and 1,2-dicarbonyl compounds.
    • Imidazole derivatives via one-pot multicomponent condensation reaction of aromatic aldehydes, benzil, aliphatic, and aromatic primary amines.

    NaBH4 supported on MgSO4 7H2O can be used as an efficient catalyst for the reduction of α, β-unsaturated carbonyl compounds to corresponding alcohols.
