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.

Gong, Zhimin;Qian, Li;Shao, Shuai;Fan, Bo;Peng, Jianbiao;Lu, Kun;Gao, Shixiang research published ã€?Effects of solvent composition on the synthesis of polydopamine Schiff base Cu complex to activate peroxymonosulfate for methyl-paraben degradationã€? the research content is summarized as follows. 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.

Fok, Emily Y.;Show, Veronica L.;Johnson, Adam R. research published ã€?Intramolecular hydroamination of trisubstituted aminoallenes catalyzed by titanium complexes of diaryl substituted tridentate imine-diolsã€? the research content is summarized as follows. The authors’ laboratory has developed catalysts based on earth abundant Ti for asym. reactions including intramol. hydroamination. Previously, Ti complexes of imine diol ligands showed improved enantioselectivity relative to complexes with bidentate amino alc. ligands. As the catalyst with the highest selectivity had di-tert-Bu substitution, the authors sought to increase the steric protection by preparing three new ligands with diaryl substitution. These ligands were readily prepared in two steps: 1st, synthesis of diaryl substituted salicylaldehydes by a Suzuki coupling and 2nd, a Schiff base condensation with a chiral amino alc. After characterizing the ligands, in situ hydroamination/cyclization with 6-methyl-hepta-4,5-dienylamine was carried out at 105-135° to give exclusively 2-(2-methyl-propenyl)-pyrrolidine with enantioselectivity up to 22%ee. Unexpected dimerization of the catalyst resulted in reduced activity, so the reaction required a catalyst loading of 10-20%.

The divergent synthesis of benzannulated 2,8-dioxabicyclo[3.2.1]octanes I [R¹ = H, 4-NO₂, 4-Cl, etc.; R² = Ph, 4-MeC₆H₄, 4-FC₆H₄, etc.] and 2,3-dihydrobenzofurans II [X= H, 4-NO₂, 4-Cl, etc.; R¹ = Ph, 4-MeC₆H₄, 4-FC₆H₄, etc.] using the concept of extended Corey-Chaykovsky reactions was reported. With this concept, 2-hydroxychalcones were treated with the Corey ylide providing highly reactive donor-acceptor cyclopropanes that were introduced in a one pot manner for further transformations. We demonstrated that the nucleophilic three-membered ring opening followed by cyclization under mild reaction conditions afforded the 2,8-dioxabicyclo[3.2.1]octane scaffold. On the other hand, heating the intermediates with a strong Bronsted acid furnished 2-phenacyl-2,3-dihydrobenzofurans. These transformations, resulting in products with crucially different heterocyclic skeletons from the same starting compounds, demonstrate the enormous potential of the extended Corey-Chaykovsky reaction.

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.

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
