In the present work, an attempt is made to establish the correlation between equilibrium constant and stabilization energy [Delta E-SE(AB)] generated from density functional reactivity theory (DFRT). The reactions chosen here are of type A + B (sic) AB (i.e., adduct formation type) between an electron acceptor, A, and an electron donor, B. The representative acceptors are methyltrioxorhenium (MTO) and substituted benzaldehydes whereas donors are 26 mono- and bidentate ligands (having N-donors) and semicarbazide. The trends of experimentally generated equilibrium constant (K) values match with those of Delta E-SE(AB) in most of the cases, both in gas phase as well as in solvent. Justification of this reliable correlation is provided analytically using the expressions of standard Gibbs free energy of reaction (i.e., Delta(r)G(theta)) and the stabilization energy expression generated by DFRT. A further analytical explanation (albeit not very rigorous) is provided through statistical thermodynamics showing how equilibrium constant (K) is related to Delta E-SE(AB) for reactions of the type A + B (sic) AB, where either A or B is a common species.

Objective. Exposure to severe stressors may alter immune function and augment inflammation and cytokine release, increasing risk of autoimmune disease. We examined whether childhood abuse was associated with a heightened risk of incident systemic lupus erythematosus (SLE). Methods. Data were drawn from the Nurses’ Health Study II, a cohort of US female nurses enrolled in 1989, followed with biennial questionnaires. We measured childhood physical and emotional abuse with the Physical and Emotional Abuse Subscale of the Childhood Trauma Questionnaire and sexual abuse with the Sexual Maltreatment Scale of the Parent-Child Conflict Tactics Scale, both administered in 2001. We identified incident SLE (>= 4 American College of Rheumatology 1997 classification criteria) through 2015. We used multivariable Cox regression models to evaluate the association between childhood abuse and SLE, accounting for potential confounders (e.g., parental education, occupation, home ownership) and mediators [e.g., depression, posttraumatic stress disorder (PTSD)]. Results. Among 67,516 women, there were 94 cases of incident SLE. In adjusted models, exposure to the highest versus lowest physical and emotional abuse was associated with 2.57 times greater risk of SLE (95% CI 1.30-5.12). We found that 17% (p < 0.0001) of SLE risk associated with abuse could be explained by depression and 23% (p < 0.0001) by PTSD. We did not observe a statistically significant association with sexual abuse (HR 0.84, 95% CI 0.40-1.77, highest vs lowest exposure). Conclusion. We observed significantly increased risk of SLE among women who had experienced childhood physical and emotional abuse compared with women who had not. Exposure to childhood adversity may contribute to development of SLE.

Quinone based compounds display activation in hypoxia, an environment prevalent in tumours. We have synthesized a bis(pyrazole) based 1,4-quinone compound suitable for metal chelation. The quinone (L2) converted to hydroquinone (H(2)L1) during the complex synthesis leading to [Ru-II(eta(6)-p-cym)(H(2)L1)Cl](PF6) (1). We found from ‘FINMR studies that in the methanolic solution L2 stoichiometrically converted to H(2)L1 while oxidizing the methanol to formaldehyde. L2 crystallized in monoclinic space group I2/a while complex 1 crystallizes in P2(1)/c. Cyclic voltammetry of the redox non-innocent L2 showed quasi-reversible (Delta Ep = 67 mV) redox behaviour with E-1/2 at 0.12 V w.r.t. NHE. Complex 1 is stable at pH 7.4 in presence of 4 mM chloride and does not hydrolyse even up to 24 h. L2 showed IC50, values of 155 and 123 mu M against metastatic breast adenocarcinoma (MDA-MB231) and pancreatic carcinoma (MIA PaCa-2) respectively. L2 gets activated by ca. 2.7-fold in hypoxia against MIA PaCa-2 cells. The mechanistic studies showed ROS accumulation and oxidation of NADH to NAD(+), which may be responsible for the cytotoxicity. The reactivity studies showed that conversion to hydroquinone by reaction with NADH or glutathione is irreversible. Complex 1 is not cytotoxic up to 100 mu M in normoxia or hypoxia. Complex 1 displays irreversible redox behavior in cyclic voltammetry displaying two overlapping oxidation peaks at 1.00 and 1.57 V w.r.t. NHE, which may be assigned to the conversion of hydroquinone to quinone and Ru-II -> Ru-III respectively.

The industrial process of hydroformylation or the oxo process has been used for many years in the production of aldehydes from alkenes. Different metals have been used as efficient catalysts for hydroformylation, in which linear and branched aldehydes are the products obtained; therefore, the development of new catalysts for hydroformylation with high selectivity to aldehydes is important. Rhodium complexes 6-9 were synthesized using [RhCl(CO)(2)](2), or [RhCl(COD)](2), with either pyrazolylpyridyl N ‘ N ‘ N pincer ligands or a pyrazolylpyridyl N ‘ N ligand. These complexes were then evaluated as catalyst precursors in the hydroformylation reaction using a variety of alkenes. The catalysts all showed activity in hydroformylation but the most active catalyst was methyl-substituted pyrazolyl-rhodium complex 7 following optimization of temperature, syngas pressure and amount of catalyst. Other olefinic substrates were used for hydroformylation in the presence of 7 under the optimum hydroformylation conditions. Undecene and dodecene as substrates only showed minimal formation of aldehydes with predominantly isomerization of the alkene being observed.

Catalyst deactivation caused by the aggregation of active metal species in the reaction process poses great challenges for practical applications of supported metal catalysts in solid-liquid catalysis. Herein, we develop a hypercrosslinked polymer integrated with N-heterocyclic carbene (NHC) as bifunctional support to stabilize palladium in heterogeneous C-C bond formations. This polymer supported palladium catalyst exhibits excellent stability in the one-pot fluorocarbonylation of indoles to four kinds of valuable indole-derived carbonyl compounds in cascade or sequential manner, as well as the representative Suzuki-Miyaura coupling reaction. Investigations on stabilizing effect disclose that this catalyst displays a molecular fence effect in which the coordination of NHC sites and confinement of polymer skeleton contribute together to stabilize the active palladium species in the reaction process. This work provides new insight into the development of supported metal catalysts with high stability and will also boost their efficient applications in advanced synthesis.

Based on the agrochemical structure of anthranilic diamides, fourteen novel N-substittitedphenyl-2-pyrazolylnicotinamides were conveniently synthesized with 2-chloro-3-cyanopyridine and 4-bromopyrazole or 3,5-dimethylpyrazole as starting materials, via an acyl transposing design strategy. Their structures were characterized by 1H NMR, 13C NMR and HRMS. The preliminary bioassay tests indicated that most of these compounds exhibited obvious insecticidal activity at the test concentration of 200 mg/L, among which N-(4-chloro-2-(ethylcarbamoyl)-6-methylphenyl)-2-(3,5-dimethyl-1H-pyrazol-1-yl)nicotinamide (II) possessed a 70% mortality rate against Mythimna separata Walker: some of the compounds displayed favorable fungicidal activities at 50 mg/L towards Physalospora piricola and Alternaria solani Sorauer, especially 2-(4-bromo-1H-pyrazol-1-yl)-N-(2-(cyclopropylcarbamoyl)-4-iodo-6-methylphenyl)nicotinamide (If) and 2-(4-bromo-1H-pyrazol-1-yl)-N-(4-chloro-2-(ethylcarbamoyl)-6-methylphenyl)nicotinamide (Ih) against Physalospora piricola, and 2-(4-bromo-1H-pyrazol-1-yl)-N-(4-chloro-2-(propylcarbamoyl)phenyl)nicotinamide (Id) against Alternaria solani Sorauer had growth inhibitory rates of 62.9%, 54.3% and 54.5%, respectively. These research results provide important reference for the further study of novel 2-pyrazolylnicotinamide derivatives.

A series of new 9,9-diethylfluorenes consisting of three side-arms each bearing a heterocyclic, bis(carboxymethyl)amino, bis(carbamoylmethyl)amino, bis(ethoxycarbonylmethyl)amino or an amino group were prepared on the basis of 2,4,7-tris(bromomethyl)-9,9-diethylfluorene. Imidazolyl, benzimidazolyl, pyrazolyl, pyrrolyl, 1,3-dioxoisoindolyl and pyridinium groups were taken into account as heterocyclic units, attached to the aromatic skeleton via -CH2-, -CH2NHCH2- or -CH2N=CH- linkers. In addition to the seventeen 2,4,7-trisubstituted 9,9-diethylfluorenes, two macrocyclic compounds were prepared on the basis of 2,7-bis(aminomethyl)-9,9-diethylfluorene. The excellent yield of the macrocyclization reaction is worth a special mention. Both the acyclic and the macrocyclic fluorene-based compounds have, among other things, the potential to act as artificial receptors for different substrates in analogy to the known receptors consisting of a benzene or biphenyl core.

CO2 capture by ionic liquids has been successfully achieved, indicating that the adsorption of CO2 plays an important role in the activation and transformation of CO2. In this work, highly efficient capture of CO2 is investigated with several novel ILs, which were prepared from bicyclic amidine (DBN) with pyrazole derivatives. Among the kinds of DBN-based ILs, it is found that the optimal absorption capacity (0.93 mol CO2/mol IL) can be achieved by [DBNH][3-MethylPyr] at 40 degrees C and atmospheric pressure. In view of analysis, the significant increase in CO2 capacity was affected by the reactivity of activated nitrogen, steric hindrance and the type of substituents. On the basis of the spectroscopic investigation and Density Functional Theory (DFT) calculation, the absorption mechanism was illustrated, it was verified that anions can react with CO2 to form carbamates. Meanwhile, charge analysis reasonably elucidated the diversity of absorption capacity in various ILs. It suggested that electric-charge distribution of activated nitrogen in pyrazole ring system can play an important role in determining the reaction of ILs with CO2. Consequently, DBN-based ILs can be excellent candidates for CO2 capture. (C) 2020 Elsevier B.V. All rights reserved.

Two novel room-temperature disulfonic acid functionalized ionic liquids derived from 3,5-dimethyl-1H-pyrazole consisting of chloride and trichlorostannate anions, 3,5-dimethyl-1,2-disulfonic acid-1H-pyrazolium chloride and 3,5-dimethyl-1,2-disulfonic acid-1H-pyrazolium trichlorostannate, have been synthesized, characterized and evaluated for their catalytic efficiency in the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones by the one-pot, three-components reaction of phthalhydrazide, an aromatic aldehyde and malononitrile or ethyl cyanoacetate under solvent-free conditions. The results have demonstrated high catalytic activity of these novel ionic liquids containing acidic SO3H groups in producing high yields of the desired products in short reaction time. The ionic liquids can be used at least four times without any noticeable decrease in catalytic activity.
