A new air-stable Si,S-chelating ligand for Ir-catalyzed directed ortho C-H borylation

A new air-stable Si,S-chelating ligand has been developed and used in an iridium-catalyzed ortho C-H borylation reaction with a broad substrate scope. This study provides the first example of using a sulfur-containing ligand in the catalytic C-H borylation process.

Recent Advances in the Development of Broad-Spectrum Antiprotozoal Agents

Infections caused by Trypanosoma brucei, Trypanosoma cruzi, Leishmania spp., Entamoeba histolytica, Giardia lamblia, Plasmodium spp., and Trichomonas vaginalis, are part of a large list of human parasitic diseases. Together, they cause more than 500 million infections per year. These protozoa parasites affect both low- and high-income countries and their pharmacological treatments are limited. Therefore, new and more effective drugs in preclinical development could improve overall therapy for parasitic infections even when their mechanisms of action are unknown. In this review, a number of heterocyclic compounds (diamidine, guanidine, quinoline, benzimidazole, thiazole, diazanaphthalene, and their derivatives) reported as antiprotozoal agents are discussed as options for developing new pharmacological treatments for parasitic diseases.

A remarkable adsorbent for removal of nitrogenous compounds from fuel: A metal-organic framework functionalized both on metal and ligand

Efficient elimination of nitrogenous compounds (NCs) from fuel is an important issue. Recently, metal organic frameworks (MOFs), both pristine and modified ones, have attracted continuous attention as an adsorbent for the purification of fuel. In this study, we used, for the first time, MOFs functionalized on both metal (via coordination on open metal site) and ligand, in the purification of fuel. A highly stable MOF, MIL-101(Cr), was modified to introduce amino groups both on the ligand and metal sites, and the NH2-MIL-101 was further reacted with oxalyl chloride to obtain a multifunctional adsorbent named OC-ED-A-M101. This adsorbent showed an outstanding performance in adsorptive denitrogenation of fuels. Or, the OC-ED-A-M101 had 11.7 and 9.3 times adsorption capacity for indole and quinoline, respectively, that of an activated carbon. Moreover, the new adsorbent showed the highest and the second highest adsorption capacity for indole and quinoline, respectively, compared with any reported MOF-based adsorbents. The noticeable performances of OC-ED-A-M101 could be interpreted with H-bonding because of ample hydrogen donor and hydrogen acceptor sites on the OC-ED-A-M101. Adsorption over other M101s could be explained with the combination of H-bonding, acid-base interaction, and base-base repulsion. Finally, the studied MOF could be easily reactivated by washing with ethanol. Therefore, OC-ED-A-M101 might be a potential adsorbent for the purification of fuel containing NCs.

Bioactivity-Guided Synthesis Accelerates the Discovery of 3-(Iso)quinolinyl-4-chromenones as Potent Fungicide Candidates

Fungal infections could cause tremendous decreases in crop yield and quality. Natural products, including flavonoids and (iso)quinolines, have always been an important source for lead discovery in medicinal and agricultural chemistry. To promote the discovery and development of new fungicides, a series of 3-(iso)quinolinyl-4-chromenone derivatives was designed and synthesized by the active substructure splicing principle and evaluated for their antifungal activities. The lead optimization was guided by bioactivity. The bioassay data revealed that the 3-quinolinyl-4-chromenone 13 showed significant in vitro activities against S. sclerotiorum, V. mali, and B. cinerea with EC50 values of 3.65, 2.61, and 2.32 mg/L, respectively. The 3-isoquinolinyl-4-chromenone 25 exhibited excellent in vitro activity against S. sclerotiorum with an EC50 value of 1.94 mg/L, close to that of commercial fungicide chlorothalonil (EC50 = 1.57 mg/L) but lower than that of boscalid (EC50 = 0.67 mg/L). For V. mali and B. cinerea, 3-isoquinolinyl-4-chromenone 25 (EC50 = 1.56, 1.54 mg/L) showed significantly higher activities than chlorothalonil (EC50 = 11.24, 2.92 mg/L). In addition, in vivo experiments proved that compounds 13 and 25 have excellent protective fungicidal activities with inhibitory rates of 88.24 and 94.12%, respectively, against B. cinerea at 50 mg/L, while the positive controls chlorothalonil and boscalid showed inhibitory rates of 76.47 and 97.06%, respectively. Physiological and biochemical studies showed that the primary action of mechanism of compounds 13 and 25 on S. sclerotiorum and B. cinerea may involve changing mycelial morphology and increasing cell membrane permeability. In addition, compound 13 may also affect the respiratory metabolism of B. cinerea. This study revealed that compounds 13 and 25 could be promising candidates for the development of novel fungicides in crop protection.

Tetrahedral copper(I) complexes of novel N,N-bidentate ligands and photophysical properties

A series of copper(I) complexes [Cu(L)(PPh3)(2)]NO3 (1-5) of bidentate ligands 2-pyridin 2 yl quinoline (L1), 4-phenyl-2-pyridin-2-yl quinoline (L2) 2-pyridin-2-yl quinoxaline (L3), 6,7-dimethyl-2-(pyridin-2-yl)quinoxaline (L4), and 4-phenyl-2-pyridin-2-yl-quinazoline (L5) have been synthesized and characterized by elemental analysis, absorption, emission, IR, H-1, C-13, P-31 NMR spectroscopies and redox method. Of these complexes [Cu(L1) (PPh3)(2)]NO3 (1), [Cu(L3)(PPh3)(2)]NO3 (3), and [Cu(L4)(PPh3)(2)]NO3 (4) are structurally characterized by single-crystal X-ray analysis. They exhibited distorted tetrahedral coordination geometries around the copper(I) center with tau(4) values of 0.77-0.86. In the solid-state, all these complexes have exhibited emission in the range of 450-750 nm and their excited-state lifetimes were measured as of 1.9-8.9 mu s. However, all the complexes were found to be weak emissive in solution due to the excited state structural rearrangement. Further, Time-dependent density-functional theory (TDDFT) calculations showed that the charge transfers are mainly caused by the contribution of HOMO-2 -> LUMO, HOMO-1 -> LUMO and HOMO -> LUMO orbitals.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 86-99-7, you can contact me at any time and look forward to more communication. Quality Control of 7-Chloroquinolin-4-ol.

Coal-Tar Dye-based Coordination Cages and Helicates

A strategy to implement four members of the classic coal-tar dye family, Michler’s ketone, methylene blue, rhodamine B, and crystal violet, into [Pd2L4] self-assemblies is introduced. Chromophores were incorporated into bis-monodentate ligands using piperazine linkers that allow to retain the auxochromic dialkyl amine functionalities required for intense colors deep in the visible spectrum. Upon palladium coordination, ligands with pyridine donors form lantern-shaped dinuclear cages while quinoline donors lead to strongly twisted [Pd2L4] helicates in solution. In one case, single crystal X-ray diffraction revealed rearrangement to a [Pd3L6] ring structure in the solid state. For nine examined derivatives, showing colors from yellow to deep violet, CD spectroscopy discloses different degrees of chiral induction by an enantiomerically pure guest. Ion mobility mass spectrometry allows to distinguish two binding modes. Self-assemblies based on this new ligand class promise application in chiroptical recognition, photo-redox catalysis and optical materials.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 86-99-7 is helpful to your research. Product Details of 86-99-7.

A fast-response turn-on quinoline-based fluorescent probe for selective and sensitive detection of zinc (II) and its application

A readily available Schiff base quinoline derivative, quinoline-2-carboxaldehyde (pyridine-2-carbonyl)-hydrazine (QCPCH), has been synthesized via a one-step condensation reaction. It is used as a turn-on fluorescent probe for detecting Zn2+ with high selectivity, sensitivity, and rapid response time of less than 3 s. In addition, the probe QCPCH shows a low detection limit of 72 nM and a large linear detection range (0-180 mu M). The mechanism of probe QCPCH for sensing Zn2+ is proposed to be based on the combined effects of chelation-induced enhanced fluorescence (CHEF) and inhibiting photoinduced electron transfer (PET); this is further demonstrated by the Job’s plot analysis, Benesi-Hilde-brand study, FT-IR spectrum, and H-1 NMR titration. Furthermore, the QCPCH is successfully applied to determine Zn2+ in real water samples, and is made into test strips for fast, convenient, quantitative and qualitative detection of Zn2+.
