The synthesis of new cationic macrocyclic host molecules is described. These macrocycles are comprised of glycoluril oligomers linked to two pyrazolium groups, which form part of a cationic wall facing into their cavities. A number of derivatives have been prepared with an objective to increasing the cavity size, and each new product has been fully characterized. Preliminary investigations of pK(a)s of Me(10)Tu-[3](2+) and an interaction of L-glutamine indicate a potential for binding anionic molecules that also carry H-bond donor groups.

Poly(3,4-ethylenedioxythiophene) (PEDOT) doped with a new sulfonated derivate from bis(3,5-dimethylpyrazol-1-yl)methane (LSA) was electrochemically synthesized and characterized by cyclic voltammetry, chronoamperometry, scanning electron microscopy, Raman spectroscopy and ultraviolet/visible spectroscopy. In addition, LSA was also fully characterized. A PEDOT:LSA modified electrode was used to study the electrochemical detection of dopamine in the presence of ascorbic and uric acid. The use of this new dopant increased the sensitivity and reduced the detection limit compared with the values observed for PEDOT doped with perchlorate.

The standard molar enthalpies of vaporization of alkyl-pyrazoles were derived from their vapor pressure-temperature dependence measured by the transpiration method as well as indirectly using solution calorimetry. Thermodynamic data on vaporization processes available in the literature were collected, evaluated, and combined with our own experimental results. Additional combustion experiments on the highly pure 1-methyl-pyrazoles helped to resolve ambiguity in the enthalpy of formation for this compound. We have evaluated and recommended a set of vaporization and formation enthalpies for the alkyl-pyrazoles at 298.15 K as the reliable benchmark properties for further thermochemical calculations. Gas phase molar enthalpies of formation of alkyl-pyrazoles calculated by the high-level quantum-chemical G4 and G3MP2 methods were in an excellent agreement with the recommended experimental data. The hydrogenation/dehydrogenation reaction enthalpies of alkyl-pyrazoles were calculated and compared with the data for other potential liquid organic hydrogen carriers. (C) 2018 Elsevier Ltd.

An operationally simple method to employ nonactivated carboxylic acids as alkylating agents in the N-alkylation of heterocycles is reported through an electrochemically driven anodic decarboxylative process. A wide substrate scope across a range of heterocycles is demonstrated along with a series of applications that significantly reduce the step count required to access such medicinally relevant structures.

The limitations of arene C-H functionalization of aryl sulfonamides containing strongly coordinating Nheterocycles were overcome using a Rh(III) catalyst. The site-selectivity of C-H carbenoid functionalization at the ortho position relative to either the sulfonamide or N-heterocycle directing groups was elegantly switched using solvents of different polarities and different additive concentrations. Importantly, sulfonamide-group-directed ortho-C-H carbenoid functionalization tolerated strongly coordinating N-heterocycles, including pyridine, pyrrole, thiazole, pyrimidine, and pyrazine. Density functional theory (DFT) calculations were performed to rationalize the reaction mechanisms and the influence of reaction polarity.

We report the syntheses, crystal structures, and characterization of the novel cis-dioxomolybdenum(VI) complexes [Tpm*(MoO2Cl)-O-VI](MoO2Cl3) (1) and [Tpm*(MoO2Cl)-O-VI](ClO4) (2), which are supported by the charge-neutral tris(3,5-dimethyl-1-pyrazolyl)methane (Tpm*) ligand. A comparison between isostructural [Tpm*(MoO2Cl)-O-VI](+) and Tp*(MoO2Cl)-O-VI [Tp* = hydrotris(3,5-dimethyl-1-pyrazolyl)borate] reveals the effects of one unit of overall charge difference on their spectroscopic and electrochemical properties, geometric and electronic structures, and O-atom-transfer (OAT) reactivities, providing new insight into pyranopterin molybdoenzyme OAT reactivity. Computational studies of these molecules indicate that the delocalized positive charge lowers the lowest unoccupied molecular orbital (LUMO) energy of cationic [Tpm*MoO2Cl](+) relative to Tp*MoO2Cl. Despite their virtually identical geometric structures revealed by crystal structures, the Mo-VI/Mo-V redox potential of 2 is increased by 350 mV relative to that of Tp*(MoO2Cl)-O-VI. This LUMO stabilization also contributes to an increased effective electrophilicity of [Tp*MoO2Cl](+) relative to that of Tp*MoO2Cl, resulting in a more favorable resonant interaction between the molydenum complex LUMO and the highest occupied molecular orbital (HOMO) of the PPh3 substrate. This leads to a greater thermodynamic driving force, an earlier transition state, and a lowered activation barrier for the orbitally controlled first step of the OAT reaction in the Tpm* system relative to the Tp* system. An Eyring plot analysis shows that this initial step yields an O Mo-IV-OPPh3 intermediate via an associative transition state, and the reaction is similar to 500-fold faster for 2 than for Tp*MoO2Cl. The second step of the OAT reaction entails solvolysis of the O Mo-IV-OPPh3 intermediate to afford the solvent-substituted Mo-IV product and is 750-fold faster for the Tpm* system at -15 degrees C compared to the Tp* system. The observed rate enhancement for the second step is ascribed to a switch of the reaction mechanism from a dissociative pathway for the Tp* system to an alternative associative pathway for the Tpm* system. This is due to a more Lewis acidic Mo-IV center in the Tpm* system.

Self-healing materials can partially or completely heal the damage done to them, and it is expected that their original function will be thereby restored. Herein, we report a novel self-healing polyvinyl (Sh-PV) containing functional polymer that reacts to thermal and ultraviolet (UV) energy. The structure of Sh-PV was characterized by fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance spectroscopy (H-1 NMR). In addition, aluminum oxide (Al2O3) inorganic nanoparticles (NPs) were added and hybridized to improve their poor self-healing efficiency and surface hardness of the coated thin film. Mechanical nanoscratch testing and scanning probe microscopy (SPM) imaging of surface using a nanoindenter were performed to investigate the healing ability of self-healing thin films. The organic-inorganic hybrid self-healing polymer thin film exhibited a 10 % improvement in surface hardness as well as 100 % healing against nanoscale damage compared to virgin self-healing polymers. Here, we discuss and evaluate the optimized method and mechanism of the self-healing system based on the results of self-healing materials and physical recovery methods for healing surface damage.

Two new Ni(II) coordination complexes of pyrazole and acetato ligands, involving nitrate and chloride counter anions, viz. [Ni(Hdmpz)(2)(CH3COO)(H2O)(3)]NO3 center dot 2H(2)O (1) and [Ni(Hdmpz)(2)(CH3COO)(H2O)(3)]Cl (2) (where Hdmpz = 3,5-dimethylpyrazole), have been synthesized in purely aqueous medium at room temperature. The complexes have been characterized by elemental analysis, FT-IR, electronic spectroscopy, PXRD, TGA and single crystal X-ray diffraction. The H-bonds established between the isostructural cationic [Ni(Hdmpz)(2)(CH3COO)(H2O)(3)](+) moieties of both complexes can be classified as anti-electrostatic H-bonds (AEHBs) and these have been studied using DFT calculations. Remarkably, in one case these AEHBs exhibit favorable interaction energies, thus indicating that the attractive nature of the H-bonds is able to compensate the pure electrostatic repulsion. The analyses of the cell viability results for the DL cell line show a significant concentration dependent decrease by compounds 1 and 2 with a negligible cytotoxic effect observed against normal cells (PBMC) in comparison to the cancer cells (DL). The cytotoxic activity of these compounds in DL cells occurs via apoptosis. Molecular docking and SAR analysis reveal that the compounds possess high binding affinities against most common cancer target proteins. (C) 2019 Elsevier Ltd. All rights reserved.

The stereoselective sulfur-nitrogen difunctionalization (aminosulfonylation) across the alkyne framework in asynmode is accomplished using sodium sulfinates and azoles, in the presence of I-2/base. This strategy is applicable to a variety of terminal alkynes, sodium sulfinates, and azoles as reaction partners, affording (Z)-beta-amino vinylsulfones in good yields.
