Description

General description

Nickel(II) sulfate hexahydrate is a hydrated nickel salt. It is used as a nickel precursor for the preparation of Ni-based catalysts.

Application

Nickel(II) sulfate hexahydrate (NiSO₄ 6H₂O) can be used as a nickel precursor for the preparation of:     

• Palladium-nickel bimetallic nanoparticles (Pd-Ni) which are used as a catalyst in the Buchwald-Hartwig amination reaction.
• NiFe₂O₄ nanoparticles (NPs) applicable for the fabrication of a glucose biosensor.

It can also be used as a recyclable catalyst in:      

• The synthesis of α-aminophosphonates via a one-pot three-component reaction of aromatic aldehydes, primary amines, and diethylphosphite.      
• Trifluoromethylation of arylamine in the presence of Langlois′ reagent (CF₃SO₂Na) as CF₃ source and potassium persulfate (K₂S₂O₈) as initiator.
