Hu, Minggang;Song, Xinfeng;Wang, Fugui;Zhang, Wenzhi;Ma, Wenhui;Han, Fuzhong research published �Ring-opening polymerization of rac-lactide catalyzed by magnesium and zinc complexes supported by an NNO ligand� the research content is summarized as follows. Two magnesium and zinc complexes were synthesized from the reaction of magnesium chloride and zinc chloride with a tridentate NNO ligand in THF. The magnesium and zinc complexes display good catalytic performance for the ring-opening polymerization of rac-lactide in the presence of benzyl alc. and a polymer with narrower mol. weight distribution is obtained. The linear relation between monomer conversion and number average mol. weight implied that the complexes were capable of catalyzing the living/controlled ring-opening polymerization of rac-lactide. Kinetic studies indicated that the ring-opening polymerization of lactide catalyzed by the catalyst contains two linear stages. In these two stages, the polymerization follows first-order kinetics for the monomer concentration The first-order dependency of the catalyst concentration was observed in the first stage. Fractional dependency upon catalyst concentration was found in the second stage. The anal. of the end group structure of the polymer indicated that the benzoxy group and hydroxyl group are the end groups of the polymer. The study on the reactions between alcs. and the complexes implied that the complexes were stable in the presence of benzyl alc. Benzyl alc. was the initiator of the polymerization and the ring-opening polymerization of rac-lactide conformed to the monomer activated mechanism.

Subsequently, all new synthesized analogs were screened for their antibacterial activities against Gram-pos. (Bacillus subtilis), and Gram-neg. bacteria (Escherichia coli), as well as for antifungal activities against Candida albicans and Aspergillus flavus. The obtained data suggest that the compounds exhibited good to excellent activity against bacterial and fungi strains. The compound (E)-2-(6-(1H-indole-3-carbonyl)-5-thioxotetrahydrothieno [3,2-b]furan-2(3H)- ylidene)-3-(1H-indol-3-yl)-3-oxopropanedithioic acid (9) showed a high binding affinity as well as an excellent biol. activity. Therefore, it could serve as the lead for further optimization and to arrive at potential antimicrobial agent.

Ghosh, Subrata;Bagchi, Sukanya;Kamilya, Sujit;Mondal, Abhishake research published ã€?Effect of ligand substituents and tuning the spin-state switching in manganese(III) complexesã€? the research content is summarized as follows. Three mononuclear manganese(III) complexes based on flexible hexadentate ligands obtained from the condensation of N,Nâ€?bis(3-aminopropyl)ethylenediamine and salicylaldehyde or salicylaldehyde with substitutions at the 5 or 3,5 positions, [Mn(X-sal₂-323)](BPh₄) (X = 5 H, (1); X = 5 Br, (2), and X = 3,5 Br, (3)) were synthesized. The impact of ligand substituents was studied by variable temperature single-crystal X-ray diffraction analyses, and magnetic, spectroscopic and electrochem. investigations. The complexes have an analogous monocationic MnN₄O₂ surrounding offered by the flexible hexadentate ligand in a distorted octahedral geometry. Complex 1 remains in the high spin state over the entire temperature range, while complex 2 shows a reversible and complete two-step thermo-induced spin-state switching. An incomplete spin-state switching from a high spin to an intermediate high-spin low-spin (1:1) state was observed for complex 3. Single-crystal X-ray structural studies show the presence of three different spin states in 2 during the occurrence of the spin-state switching process. Electrochem. investigations showed that the reduced state of manganese(III) centers in 3 is easily accessible in comparison to complexes 1 and 2.

Solvent composition plays an important role in the synthesis of metal complex materials, but to date little work on this issue has been reported. Herein, a unique Schiff base Cu complex catalyst (DPDA-Cu-95EtOH) was designed based on polydopamine (PDA) and 3, 5-dibromosalicylaldehyde (DBSA), and the influence of H₂O added during the synthesis process on its catalytic performance towards peroxymonosulfate (PMS) activation was comprehensively investigated. Our results demonstrated that adding a small amount (5%, v:v) of H₂O to the solvent absolute ethanol (EtOH) can greatly increase the Cu loading (from 3.56 at% to 10.30 at%) on the catalyst, which significantly enhanced its catalytic ability, and promoted the removal of MeP for about 4.6 times higher than that synthesized without addition of H₂O. ESR (EPR) and quenching tests revealed that ¹O₂, OH and SO^–₄ were responsible for the degradation of Methyl-paraben (MeP). Moreover, the DPDA-Cu-95EtOH/PMS system not only showed excellent stability and reusability, but also exhibited considerable removal efficiency of MeP in real wastewater. Overall, this study provides new insights into the controllable synthesis of Schiff base metal complex used for the efficient activation of PMS to remove micropollutants in wastewater.

Our results demonstrated that adding a small amount (5%, v:v) of H₂O to the solvent absolute ethanol (EtOH) can greatly increase the Cu loading (from 3.56 at% to 10.30 at%) on the catalyst, which significantly enhanced its catalytic ability, and promoted the removal of MeP for about 4.6 times higher than that synthesized without addition of H₂O. ESR (EPR) and quenching tests revealed that ¹O₂, OH and SO^–₄ were responsible for the degradation of Methyl-paraben (MeP). Moreover, the DPDA-Cu-95EtOH/PMS system not only showed excellent stability and reusability, but also exhibited considerable removal efficiency of MeP in real wastewater. Overall, this study provides new insights into the controllable synthesis of Schiff base metal complex used for the efficient activation of PMS to remove micropollutants in wastewater.

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., 90-59-5.
