Fe3O4 nanoparticles were modified with pyridyl-triazole ligand and the new magnetic solid was applied for the stabilization of very small and uniform gold nanoparticles. The resulting magnetic material, Fe3O4@PT@Au, was characterized using various methods. These gold nanoparticles on a magnetic support were applied as an efficient heterogeneous catalyst for the three-component reaction of amines, aldehydes and alkynes (A3 coupling) in neat water with 0.01 mol% Au loading. Using magnetic separation, this catalyst was recycled for seven consecutive runs with very small decrease in activity. Characterization of the reused catalyst did not show appreciable structural modification. In the experiment, the researchers used many compounds, for example, 2-(2-Bromoethyl)pyridine hydrobromide (cas: 72996-65-7Related Products of 72996-65-7).
2-(2-Bromoethyl)pyridine hydrobromide (cas: 72996-65-7) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Related Products of 72996-65-7
