Four new coordination compounds of nickel (II) with derivatives of N,N-bis(pyrazol-1-ylmethyl)propylamine were synthesized; their composition and structure were confirmed with IR-spectroscopy and elemental analysis. The structures of products 13 and 15 were unambiguously established in an X-ray diffraction study. Compounds 13 and 15 crystallize in the orthorhombic space groups Pna2(1) and P2(1)2(1)2(1) correspondingly and represent a monomeric octahedral nickel complexes, that are typical for tridentate scorpion-type ligands. New method for immobilization of nickel complexes with derivatives of N,N-bis(pyrazol-1-ylmethyl)propylamine on silica gel modified with aminopropyl groups was proposed. The EXAFS/XANES analysis indicated that Ni atom in the supported complexes adopt almost octahedral geometry, being partly surrounded by nitrogen atoms from organic ligand and partly grafted to silica surface through silanol groups, with Br- in outer coordination sphere. Both the original and the supported complexes, when activated with Et2AlCl or Et3Al2Cl3, catalyze ethylene oligomerization with the predominant formation of butene isomers. Generally, the immobilized complexes show higher activity and better selectivity towards 1-butene formation.

In the title bicyclic trinuclear pyrazolate aminoalcohol complex, [Cu-3(C5H7N2)(2)-(C6H14NO3)(2)]Br-2 center dot 1.5H(2)O, the central Cu atom lies on a center of symmetry and is involved in the formation of two five-membered rings. It has a coordination number of 4, is in a distorted tetrahedral environment and is connected by the bridging oxygen atoms of the deprotonated OH groups of different aminoalcohol groups, and by the N atoms of deprotonated dimethylpyrazole ligands. The peripheral Cu atom is in a trigonal-bipyramidal coordination environment formed by the nitrogen atom of the deprotonated bridging dimethylpyrazole unit, the bridging oxygen atom of the deprotonated OH group, two oxygen atoms of the protonated hydroxy groups and the nitrogen atom of triethanolamine. One of the C atoms and the Br- anion were found to be disordered over two positions with occupancy factors of 0.808 (9):0.192 (9) and 0.922 (3):0.078 (3), respectively.

Unsymmetrical pincers have been shown to be better than the corresponding symmetrical pincers in several catalysis reactions. A new unsymmetrical PNN propincer, 2-(3,5-dimethylpyrazolylmethyl)-5-(diphenylphosphinomethyl)-pyrrole (1), was synthesized from pyrrole through Mannich bases in a good yield. In addition, the new byproduct 2-(3,5-dimethylpyrazolylmethyl)-5-(dimethylaminomethyl)-N-(hydroxymethyl)pyrrole was also isolated. The reaction of 1 with [PdCl2(PhCN)(2)] and Et3N in toluene yielded [PdCl-{C4H2N-2-(CH(2)Me(2)pz)-5-(CH2PPh2)-kappa P-3,N,N}] (2). The analogous reaction between 1 and [NiCl2(DME)] or NiX2 (X = Br, I) in the presence of NEt3 in acetonitrile afforded [NiX{C4H2N-2-(CH(2)Me(2)pz)-5-(CH2PPh2)-kappa P-3,N,N}] (3; X = Cl, Br, I). All complexes were structurally characterized. The norbornene polymerization behaviors of the unsymmetrical pincer complexes 2 and 3 in the presence of MMAO or EtAlCl2 were compared with those of the symmetrical pincer complexes chloro[2,5-bis(3,5-dimethylpyrazolylmethyl)pyrrolido]-palladium(II) (NNN), chloro[2,5-bis(diphenylphosphinomethyl)pyrrolido]palladium(II), and chloro[2,5-bis(diphenylphosphinomethyl)pyrrolido]nickel(II) (PNP) at different temperatures. The PNN and NNN complexes exhibited far greater activity on the order of 10(7) g of PNB/mol/h, with quantitative yields in some cases, in comparison to the PNP pincer palladium and nickel complexes. This trend was also supported by the Pr-i group substituted PNP nickel and palladium pincer complexes. These polymerization behaviors are explained using steric crowding around the metal atom with the support of NMR studies and suggested that the activity increases as the N-pyrazole donor increases. Polymers were characterized by H-1 NMR, IR, TGA, and powder XRD methods.

In this study, three triazole based azo molecules [3-amino-4-[1H-1,2,4-triazole-3-yldiazenyl]-1H-pyrazole-5-ol (1), 3-[(3,5-dimethyl-1H-pyrazole-4-yl)diazenyl]-1H-1,2,4-triazole (2) and 4-[1H-1,2,4triazole-3yldiazenyl]benzene-1,3-diol (3)] were, synthesized and characterized by using 1H NMR, FTIR, UV-vis and mass spectra. The molecular structure, vibrational spectroscopic data, electronic transition absorption wavelengths, HOMOs and LUMOs analyses, molecular electrostatic potential (MEP) and potential energy surface (PES) diagrams were calculated by using DFT/B3LYP method with 6-311G(d,p) basis set. NMR chemical shift calculations were performed by using the gauge-invariant atomic orbital (GIAO) method. The spectroscopic results obtained from quantum chemical calculations of the 1, 2 and 3 molecules were in good agreement with the experimental data. Antibacterial activities of the 1, 2 and 3 were investigated against four different bacterial cultures. Although 1 molecule did not show very good antibacterial activity, 2 and 3 showed good activity against Staphylococcus aureus at a MIC of 250 and 62.5 mg/mL, respectively. Druglikeness and some of the pharmacokinetic properties of the 1, 2 and 3 were also examined. In addition, molecular docking studies were performed to investigate the antibacterial properties of synthesized compounds by in silico method. For this purpose, beta-ketoacyl-acyl carrier protein (ACP) synthase III (KAS III) and lipoteichoic acid synthase (LtaS) inhibitory properties of 1, 2 and 3 molecules were investigated. Although all of the synthesized compounds showed antibacterial properties according to the results of the molecular docking studies, the best results were obtained by the compound 3 which interacts with both KAS III and LtaS with binding energy of -7.17 and -7.53 kcal/mol, respectively.

A new convenient and versatile halogenating system (R(4)NHal/NOHSO4), giving straightforward and general access to halogenated 3,5-diaryl- and alkylarylisoxazoles, pyrazoles and electron-rich benzenes from the corresponding scaffolds, is suggested. The method provides excellent regioselectivity, scalability to the gram scale, and a broad scope for both aromatics and halogens. A three-step, one-pot reaction protocol was developed, and a series of 3,5-diaryl-4-haloisoxazoles has been efficiently synthesized from 1,2-diarylcyclopropanes under suggested nitrosating-halogenating conditions.

Cationic fac-[Re(CO)(3)(pz*H)(pypzH)]OTf (pz*H = pyrazole, pzH; 3,5-dimethylpyrazole, dmpzH; indazole, indzH; 3-(2-pyridyl)pyrazole, pypzH) were obtained from fac[ReBr(CO)(3)(pypzH)] by halide abstraction with AgOTf and subsequent addition of the corresponding pyrazole. Successive deprotonation with Na2CO3 and NaOH gave neutral fac[Re(CO)(3)(pz*H)(pypz)] and anionic Na{fac-[Re(CO)(3)(pz*)(pypz)]} complexes, respectively. Cationic fac-[Re(CO)(3)(pz*H)(pypzH)]OTf, neutral complexes fac-[Re(CO)(3)(pz*H)(pypz)], and fac-[Re(CO)(3)(pypz)(2)Na] were subjected to photophysical and electrochemical studies. They exhibit phosphorescent decays from a prevalently (MLCT)-M-3 excited state with quantum yields (F) in the range between 0.03 and 0.58 and long lifetimes (tau from 220 to 869 ns). The electrochemical behavior in Ar atmosphere of cationic and neutral complexes indicates that the oxidation processes assigned to Re-I -> Re-II occurs at lower potentials for the neutral complex compared to cationic complex. The reduction processes occur at the ligands and do not depend on the charge of the complexes. The electrochemical behavior in CO2 saturated media is consistent with CO2 electrocatalyzed reduction, where the values of the catalytic activity [i(cat)(CO2)/i(cat)(Ar)] ranged from 2.7 to 11.5 (compared to 8.1 for fac-[Re(CO)(3)Cl(bipy)] studied as a reference). Controlled potential electrolysis for the pyrazole cationic (3a) and neutral (4a) complexes after 1 h affords CO in faraday yields of 61 and 89%, respectively. These values are higher for indazole complexes and may be related to the acidity of the coordinated pyrazole.

All of the synthesized ligands and complexes have been characterized by physicochemical and spectroscopic methods and the crystal structures of [Ni(EtNCSPz)(2)] (1a) and [Ni(PhNCSPz(Me3))(2)] (4a) have been determined by X-ray diffraction analysis. The X-ray crystal structure of both the complexes describe a square planar coordination geometry. The electrochemical studies show that the synthesized complex is an electrochemically active species, furthermore, substitution electron donating groups on the ligands shift the reduction and oxidation potentials to negative values. Antibacterial activity results indicate these complexes possess high activity against gram-positive and gram-negative bacteria compare to the free ligands. (C) 2020 Elsevier Ltd.
