Reference of 13395-16-9, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps. In an article, authors is Sousa, once mentioned the application of Reference of 13395-16-9, Name is Bis(acetylacetone)copper,molecular formula is C10H16CuO4, is a conventional compound.
The interaction of 2-pyridinecarboxaldehyde with N-tosyl-1,2-diaminobenzene leads to the isolation of two different products, {3-[ethoxy(2-pyridyl)methyl]-1-[(4-methylphenyl)sulfonyl]-2-(2-pyridyl)-2,3- dihydro-1H-benzo[d]imidazole}, L1, and {1-[(4-methylphenyl)sulfonyl]-2-(2-pyridyl)-2,3-dihydro-1H-benzo[d] imidazole}, L2, but not to the expected Schiff base 1-[(4-methylphenyl)sulfonamido]-2-[(2-pyridylmethylene)amino]benzene, HL3. Two kinds of complexes, containing the potentially tridentate and monoanionic [L3]- as a ligand, were obtained by different routes. ML3(p-Tos)(H2O)n complexes (p-TosH = p-toluenesulfonic acid; M = Co, Cu, Zn; n = 1-3) have been isolated by electrolysis of a solution phase composed of L1 and p-toluenesulfonic acid, using metal plates as the anode. Metal complexes of composition ML32(H2O)n (M = Mn, Co, Cu, Zn; n = 0-2) were obtained by template synthesis from M(acac)2, 2-pyridinecarboxaldehyde and N-tosyl-1,2-diaminobenzene. All these compounds have been characterised by elemental analyses, magnetic measurements, IR, mass spectrometry and, in the case of M = Zn, by 1H NMR spectroscopy. CuL3(p-Tos)(H2O), 1, ZnL3(p-Tos)(H2O), 2, CoL32, 3, CuL32, 4 and ZnL32 · 2CH3CN, 5, were also crystallographically characterised.
