"Click chemistry" in zeolites: Copper(I) zeolites as new heterogeneous and ligand-free catalysts for the huisgen [3+2] cycloaddition

Article abstract of DOI:10.1002/chem.200800479

For the first time, copper(I)-exchanged zeolites were developed as catalysts in organic synthesis. These solid materials proved to be versatile and efficient heterogeneous, ligand-free catalytic systems for the Huisgen [3+2] cycloaddition. These cheap and
