Abstract
In this work, a new metal–organic framework (Cu(II)@UiO-66-AzPh) was prepared by functionalizing UiO-66-NH2 with 2,4-dihydroxy-5-para-tolyl-azo benzaldehyde (AzPh) and then fixing the copper cation on its surface. The formation of this nanocatalyst has been confirmed by SEM, IR, mapping, EDX, BET, CHN, TEM, and TGA analyses. Then, the catalytic activity of Cu(II)@UiO-66-AzPh was evaluated in the three-component reactions of benzaldehydes, aniline derivatives, and ethyl pyruvate, which led to 1,5-dihydro-2H-pyrrole-2-ones in high to excellent yields (78%–97%). The high catalytic activity of the synthesized catalyst can be due to the increased dispersion and presence of the copper cation (as a Lewis acid) in Cu(II)@UiO-66-AzPh. This nanocatalyst is very efficient and stable and can be easily separated and used up to 5 times without any significant loss of activity.
期刊介绍：
All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
