A practical and efficient protocol for Ag/Ru-cocatalyzed regioselective C-H amination of 8-hydroxyquinoline esters with pyrazoles was developed, This reaction proceeded smoothly via a photoredox-mediated direct C-H/N-H oxidative coupling process. The remarkable features of this reaction include the wide substrate scope, mild reaction conditions and high regioselectivity at the C4 site of the quinolinyl moiety. (C) 2019 Elsevier Ltd.

Two coordination complexes of Cu(II) and Co(II) involving 3,5-dimethylpyrazole viz. { [Cu(mu-O,O’-SO4) (Hdmpz)(2)(H2O)]center dot 2H(2)O}(n) (1) and [Co(Hdmpz)(4)(H2O)(2)Cl-2 (2) (where Hdmpz = 3,5-dimethylpyrazole) have been synthesized in purely aqueous medium at room temperature. Crystal structure of complex 1 consists of a polymeric chain of distorted square pyramidal Cu(II) centers bridged by bidentate sulfato ligands. The polymeric chain in 1 has been stabilized by N-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions. Particularly relevant is the polymeric chain in 1, since in addition to the afore mentioned non-covalent contacts, unprecedented chalcogen bonding interactions involving the sigma-hole at the tetrahedral sulfur atom are observed and characterized using theoretical calculations. To our knowledge, sigma-hole chalcogen bonding interactions involving tetrahedral sulfur atom have not been previously reported in the literature. The lattice water molecules self assembles the polymeric chains of 1 into a 3D supramolecular architecture via C-H center dot center dot center dot O hydrogen bonding interactions. The cationic units in the crystal structure of 2 self assembles via O-H center dot center dot center dot Cl, N-H center dot center dot center dot Cl and C-H center dot center dot center dot Cl weak hydrogen bonding interactions into a 2D supramolecular architecture induced by chloride anions in the lattice. PXRD patterns of 1 and 2 demonstrate good phase purity of the complexes. In addition, the thermal behaviour of the complexes has also been investigated.

Some new compounds, 2-(3,5-dimethyl-1H-pyrazol-1-yl)-4-substituted acetophenone oximes [4a-4f; here, 4-substituent = H (a), Br (b), Me (c), Cl(d), NO2 (e), F (f)] were synthesized by the reaction of 2-(3,5-d imethyl-1H-pyrazol-1 -yl)-1 -arylethano nes with hydroxylamine hydrochloride. These compounds were characterized by analyzing their IR, H-1, C-13 NMR and mass spectral data. Compounds 4a-4f were further converted into their silver complexes (4g-4l) and chemical structures of which were established on the basis of their X-ray crystallographic data. The antibacterial and DNA photocleavage activity studies were carried out for all the synthesized compounds 4a-4l, and it has been found that compound 4l displayed an excellent level of antibacterial and DNA photocleavage activity. Among the series, Ag-complexes (4g-4l) displayed excellent antibacterial activity against four bacterial strains using Ciprofloxacin as a standard drug. In DNA photocleavage study, it has been observed that compounds 4a, 4e, 4f degraded both forms of DNA, whereas their Ag-complexes degraded DNA completely even at a very low concentration. The intermolecular interactions present in 4g and 4h were described by decomposing Hirshfeld surfaces into 2D fingerprint plots. It was observed that non-polar interactions contribute dominantly in overall intermolecular interactions exit in crystals of both the compounds. (C) 2020 Elsevier Ltd. All rights reserved.

A metal-free promoted direct oxidative C-N bond coupling of quinoxalinones and azoles for the rapid and effective synthesis of potent pharmaceutical important 3-(azol-1-yl)quinoxalin-2-one has been developed. Employing PIDA as the easily available mediator, the desired coupling products were isolated in moderate to excellent yields with a good substrate scope under operational simplicity and mild reaction conditions. Preliminary mechanistic studies suggested that a radical process is likely to be involved in the reaction. (C) 2020 Elsevier Ltd. All rights reserved.

The search for new fluorescent materials with high quantum yields has been the focus of research, considering the diverse applications that fluorescent materials present. In this study, ferrocenyl pyrazolyl (L1) and ferrocenyl triazolyl (L2) ligands and their palladium metal complexes (1 and 2) were synthesized to investigate their fluorescence properties. While the pyrazolyl ligand was prepared through a ligand substitution reaction, synthesis of the triazolyl derivative involved the [3 + 2] azide-alkyne using click chemistry. All the prepared compounds have been characterized by NMR and IR spectroscopy, elemental analysis, mass spectrometry and single-crystal X-ray crystallography. These air-stable compounds were prepared in moderate to good yields (70% and 83%). The ferrocenyl-pyrazolyl L1 and ferrocenyl-triazolyl L2 ligands showed near-infrared (NIR) emission bands with quantum yields of 20% and 26% respectively. The addition of the Pd2+ ions results in the reduction of fluorescence intensity and quantum yield. Such fluorescent properties demonstrate their potential use in bio-analysis and as fluorogenic probing. (C) 2020 Elsevier B.V. All rights reserved.

Comparison of various organic compounds such as glycols, amines and alkanolamines as organocatalysts in amidation of fatty acid methyl esters with 3-(dimethylamino)-1-propylamine was made for the first time. It was experimentally detected that catalysts containing OH-groups (alcohols, glycols, glycerol and aminoalcohols) influence the reaction rate. Moreover, catalytic effect is depending on the catalysts geometry significantly. 1,5-diols (e. g. diethylene glycol and diethanolamine) were found to accelerate the reaction more than other OH-groups containing additives. It was supposed, that this catalytic effect is caused by specific associative interactions between reactants and 1,5-diols, what was confirmed by quantum mechanics calculations. Catalysts concentration effects on the reaction rate were also investigated.

The development of an intermolecular and enantioselective aza-Wacker reaction is described. Using indoles as the N-source and a selection of alkenols as the coupling partners selective beta-hydride elimination toward the alcohol was achieved. This strategy preserves the newly formed stereocenter by preventing the formation of traditionally observed enamine products. Allylic and homoallylic alcohols with a variety of functional groups are compatible with the reaction in high enantioselectivity. Isotopic-labeling experiments support a syn aminopalladation mechanism for this new class of aza-Wacker reactions.
