Abstract :
The reaction of the functionalized mesoporous SBA-15 in absolute ethanol
with copper (II) acetate aorded a novel CuII-Schi base/SBA-15 catalyst. The compound
CuII-Schi base/SBA-15 was characterized by IR spectroscopy, small-angle X-ray
diraction (SAX), Energy Dispersive X-ray Spectroscopy (EDXS), X-ray Absorption Near
Edge Structure (XANES), Scanning Electron Microscope (SEM), Transmission Electron
Microscope (TEM), and N2 adsorption/desorption studies. Further, the catalytic activity
of this well-dened material was tested in three-component Copper-catalyzed Azide-Alkyne
Cycloaddition (CuAAC) reactions to obtain 1,4-disubstituted-1,2,3-triazoles in good to
excellent yields from an organic halide, sodium azide, and alkyne in water as a green
solvent. More importantly, the catalyst can be recovered and reused eciently up to ve
consecutive cycles with negligible loss of catalytic activity.
