General description
Copper(II) sulfate pentahydrate is a Lewis acid catalyst commonly used to promote acid-catalyzed organic transformations. It can also act as an effective redox catalyst in combination with other mixed oxidizing agents.
Application
Copper(II) sulfate pentahydrate can be used as a catalyst:
It can also be used as a template in the synthesis of copper(II) ion-imprinted polymers using vinylpyridine and methacrylic acid as functional monomers. This polymer is used to quantify Cu2+ ion by using flame atomic absorption spectroscopy.
- In acetylation of alcohols and phenols in the presence of acetic anhydride.
- To synthesize various ynamides via intramolecular coupling of amides with alkynyl bromides.
It can also be used as a template in the synthesis of copper(II) ion-imprinted polymers using vinylpyridine and methacrylic acid as functional monomers. This polymer is used to quantify Cu2+ ion by using flame atomic absorption spectroscopy.
Features and Benefits
CuSO4.5H2O is an inexpensive, safe catalyst to be used in various organic transformations. It can also be recovered and reused in another reaction.

Three novel metal-organic frameworks (MOFs), [Cu(1)SO4].H2O (4), [Cu2(2)2(SO4)2].4H2O (5) and [Cu(3)(H2O)]SO4.5.5H2O (6), were obtained by hydrothermal reactions of CuSO4.5H2O with the corresponding ligands, which have different flexibility. The structures of the synthesized complexes were determined by single-crystal X-ray diffraction analyses.

Azoamides, previously established as bioactive intracellular GSH-depleting agents, were decorated with a terminal alkyne moiety to 4 and then were transformed, by copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC), into different ligand-arm functionalized azoamides 6. Azides 5 having ligand-arms amenable for binding to
