Abstract
Two different diamines, namely, Troger base and dimethylethylene diamine (DMEDA) functionalized with dislane group have been condensed with silica precursors to form mesoporous hybrid organic-inorganic materials. After introduction of copper, the Cu-diamine complexes are produced. These hybrid solids have been fully characterized and are active catalysts for the S-arylation of aryl iodides and bromides with thiophenols and disulfides. Additionally the hybrids show catalytic activity for the cycloaddition reaction between azides and phenylacetylenes. The reaction conditions determine the recover and reuse of the solid.
