General description

Nickel(II) sulfate hexahydrate (NiSO4 · 6H2O) is commonly used as a nickel precursor and catalyst in the various organic synthesis.

Application

Nickel(II) sulfate hexahydrate can be used:
  • As a catalyst for the synthesis of α-aminophosphonates by a condensation reaction of aromatic aldehydes, primary amines, and diethylphosphite.
  • In the synthesis of nickel (II) hexamethylenetetramine complex [Ni(HMTA)2 (NCS)2(H2O)2]H2O with thiocyanate coligand.
  • As a nickel source in the synthesis of nanosized nickel phosphides by the solvothermal route using red phosphorus as the P-3 precursor.
