说明

一般描述

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.
 

应用

Copper(II) sulfate pentahydrate can be used as a catalyst:      
  • 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.
 

特点和优势

CuSO4.5H2O is an inexpensive, safe catalyst to be used in various organic transformations. It can also be recovered and reused in another reaction.
