Ngcobo, Makhosonke;Nose, Holliness;Jayamani, Arumugam;Ojwach, Stephen O. research published 《 Structural and ethylene oligomerization studies of chelating (imino)phenol Fe(II), Co(II) and Ni(II) complexes: an experimental and theoretical approach》, the research content is summarized as follows. The metal complexes [Fe(L1)2] (Fe1); [Fe(L2)2] (Fe2); [Fe(L3)2] (Fe3); [Co(L1)2] (Co1); [Co(L2)2] (Co2); [Co(L3)3] (Co3); [Ni(L1)2] (Ni1); [Ni(L2)2] (Ni2) and [Ni(L3)3] (Ni3); where L = 2,4-dibromo-6-((pyridin-2-ylimino)methyl)phenol (L1H), 2,4-dibromo-6-(((4-methylpyridin-2-yl)imino)methyl)phenol (L2H) and 2,4-dibromo-6-((quinolin-8-ylimino)methyl)phenol (L3H), were synthesized in good yields. The complexes were characterized using IR spectroscopy, UV-visible spectroscopy, mass spectrometry, magnetic moment measurements, elemental anal., and x-ray crystallog. The mol. structures of complexes Fe3a (oxidized form of Fe3) and Ni3 confirmed the isolation of bis(chelated) tridentate bound octahedral compounds Activation of the complexes with the EtAlCl2 co-catalyst produced active catalysts in the ethylene oligomerization reactions to afford mainly C4 and C6 oligomers. The catalytic activities and product distribution were largely controlled by the nature of the ligand and the metal atom. D. functional theory calculations were used to study the influence of complex properties and global descriptors in the ethylene oligomerization reactions. The stability and magnitude of the charge of the metal atom appear to drive the overall catalytic activities of the complexes.
90-59-5, 3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes.
3,5-Dibromosalicylaldehyde, also known as 3,5-Dibromosalicylaldehyde, is a useful research compound. Its molecular formula is C7H4Br2O2 and its molecular weight is 279.91 g/mol. The purity is usually 95%.
3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes. 3,5-Dibromosalicylaldehyde can be used in the synthesis of Schiff base and can be used as reactant for synthesis of Schiff base ligands which forms mononuclear complexes with copper(II), nickel(II), zinc(II) and cobalt(II).
3,5-Dibromosalicylaldehyde is a copper complex that has been synthesized from 3,5-dibromosalicylaldehyde and copper chloride. FTIR spectroscopy revealed that the coordination geometry of the copper complex is octahedral with two nitrogen atoms in the equatorial plane. The presence of hydrogen bonding interactions was confirmed by homologous protein adsorption experiments. This chemical structure was determined using X-ray crystallography and fluorescence probe experiments. The copper complex showed high affinity for malonic acid, which is an ester hydrochloride. The molecular mechanism of this interaction is based on adsorption, which occurs through hydrogen bonding interactions and hydrophobic interactions. Structural analysis revealed that the polymeric matrix consists of a three-dimensional network of crosslinked chains, while FTIR analysis indicated a possible disulfide bond between two cysteine residues., Safety of 3,5-Dibromo-2-hydroxybenzaldehyde
