And the article was included in Zeitschrift fuer Naturforschung, B: A Journal of Chemical Sciences in 2017.Category: copper-catalyst This article mentions the following:
Two complexes, {Mn(hfac)2(BIPMO)}n (1), {Cu(hfac)2(BIPMO)}n (2) [hfac = 1,1,1,5,5,5-hexafluoro-pentane-2,4-dionato(-), BIPMO = bis(4-(1H-imidazol-1-yl)phenyl)methanone], with the V-shaped ligands were synthesized and characterized by IR spectroscopy, elemental analyses, along with single-crystal x-ray diffraction analyses. The x-ray diffraction studies have shown that the metal ions in 1 and 2 are both six-coordinated to two nitrogen atoms of two BIPMO ligands and four oxygen atoms of two hfac ligands to form a distorted octahedral geometry. Each BIPMO ligand acts as a bridging ligand to link two adjacent metal(II) atoms to form a helical chain in the crystal structure. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Category: copper-catalyst).
copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to low toxicity and inexpensive, earth-abundant. Copper nanoparticles can also catalyze the coupling reaction of phenols, thiols, xanthogenates, nitrogen-containing nucleophiles, selenium ruthenium nucleophiles and the like.Category: copper-catalyst
