Jiao, Yan-Ping;Shi, Hao-Yu;Zhou, Wen-Yan;Jia, Ai-Quan;Shi, Hua-Tian;Zhang, Qian-Feng research published ã?Syntheses, characterizations and structures of organometallic tri- and tetra-dentate ferrocenoyl enaminone ligands and their unsymmetrical Schiff base derivativesã? the research content is summarized as follows. Condensation of ferrocenoylacetone with alkyl or aryl diamine (1,2-diaminoethane, 1,3-diaminopropane, 1,4-diaminocyclohexane, 1,4-diaminobenzene) afforded three tridentate ferrocenoyl enaminone ligands (Fc-C(O)CH:C(CH3)NHR1) (L1: R1 = CH2CH2NH2; L3: R1 = 4-C6H4NH2; L5: R1 = 4-C6H10NH2; Fc = ferrocenyl) and four sym. tetradentate ferrocenoyl enaminone ligands [(Fc-C(O)CH:C(CH3))NH]2R (L2: R = CH2CH2; L4: R = 4-C6H4; L6: R = 4-C6H10; L8: R = CH2CH2CH2). Of which, L3 was further reacted with appropriate substituted salicylaldehydes to give unsym. Schiff base ligands Fc-C(O)CH:C(CH3)NH(4-C6H4)N:CH(2-OHAr) (L9: Ar = C6H4; L10: Ar = 5-ClC6H3; L11: Ar = 5-NO2C6H3; L12: Ar = 3,5-Br2C6H2; L13: Ar = 3,5-tBu2C6H2). All new ligands L3–L6, L8 and L9–L13 were characterized by 1H NMR, 13C NMR, FT-IR, and UV-Vis spectroscopies along with their electrochem. properties. Moreover, mol. structures of ligands L2–L4, L8 and L9 have been established by single-crystal x-ray crystallog.
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., Category: bromides-buliding-blocks
