Zou, Dong-Hui;Liang, Min;Chen, Wei research published 《 Synthesis, X-ray crystal structures and catalytic epoxidation of oxidovanadium(V) complexes with aroylhydrazone and ethyl maltolate ligands》, the research content is summarized as follows. Two oxidovanadium(V) complexes, [VOL1L] (1) and [VOL2L] (2) (L = Et maltolate), derived from the aroylhydrazones 4-bromo-N′-(2-hydroxy-5-methylbenzylidene)benzohydrazide (H2L1) and N′-(3,5-dibromo-2-hydroxybenzylidene)-4-methoxybenzohydrazide (H2L2), resp., have been synthesized and characterized by elemental anal., IR and electronic spectroscopy. Structures of the complexes were further confirmed by single crystal X-ray determination The V atoms in the complexes are coordinated by the ONO donor atoms of the aroylhydrazone ligand, OO donor atoms of the Et maltolate ligand, and one oxido O atom, forming octahedral coordination. The complexes function as effective olefin epoxidation catalysts with hydrogen peroxide as terminal oxidant and sodium hydrogen carbonate as a co-catalyst.
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., Computed Properties of 90-59-5
