Sulfuric acid and aromatic compounds are abundant in the atmosphere and play an important role in aerosol nucleation and growth. The main objective of this work is to provide molecular level description of pre-nucleation clusters formed by these species. Our approach is based on size- and compositionselective generation of anionic clusters, consisting of sulfuric acid and series of aromatic carboxylates (ArCOO-; Ar =Phenyl, o-, m-, and p-CH3C6H4 ), and their subsequent characterization using photoelectron spectroscopy and quantum chemical calculations. The photoelectron spectra show that formation of these clusters is accompanied by a significant increase of electron binding energies, implying significant stabilization gained from electron delocalization upon complexation. Comparison between the experimental and calculated results suggests that under low temperature conditions these clusters behave more like a complex of sulfuric acid and aromatic carboxylate, (H2SO4)(ArCOO-), despite the fact that ArCOO- has much higher proton affinity than HSO4-. Similar result has been previously reported for sulfuric acid formate cluster [Hou, Wang, and Valiev, J. Am. Chem. Soc. 139 (2017) 11321-11324], and indicates that interaction energy gained though the formation of these clusters is sufficient to counteract proton affinity imbalance. The calculated intermolecular binding energies (BEs), Gibbs free energies (Delta G), and evaporation rates (gamma) show that these (H2SO4)(ArCOO- ) clusters are extremely stable, with BEs of similar to 54 kcal/mol, Delta G of similar to-40 kcal/mol, and gamma of 10(-20) s(-1) . The experimental and computational results reported in this work suggest that aromatic acids may play a significant role in facilitating the early stages of sulfuric acid nucleation.

An efficient synthesis of tert -butyl peroxides through TBAI-promoted acyloxylation-peroxidation of alkenes by using a carboxylic acid and tert -butyl hydroperoxide was developed. The synthetic utility of our method is enhanced by simple manipulations, easily available starting materials, and a wide substrate scope.

SCM-198 (Leonurine) has attracted great attention due to its cardioprotective effects in myocardial infarction (MI). However, no systematic modifications and structure-activity relationship (SAR) studies could be traced so far. In this study, 35 analogs of SCM-198 were designed, synthesized and their cardioprotective effects were evaluated. The cell viability assay on cardiomyocyte cell line H9c2 challenged with H2O2 showed that several analogs exhibited more potent cytoprotective effects than SCM-198 at 1 mu M and 10 mu M concentrations. LDH release level in cells treated with 1 mu M 14o was comparable with cells treated with 10 mu M SCM-198. Results of Bcl-2 expression and caspase-3 activation accordingly indicated higher protective activity of 14o than SCM-198. Moreover, in a mouse model of MI, the mice pretreated with 14o had much lower infarct size compared with that of SCM-198. The mechanism study suggested that 14o improved cardiac morphology and reduced apoptosis of cardiomyocytes in the border zone of infarction, as proved by H&E and TUNEL staining.

Chemical synthesis was used for the functionalization of graphene oxide using Meta toluic acid. Various covalent and non covalent attachments of functional groups were used for surface modification of GO due to the presence of oxygen groups on the surface of GO. Modified graphene oxide was obtained by esterification reaction. The characterization of GO and modified GO (FGO) was done using X-ray diffraction (XRD), Fourier transform infra red spectroscopy (FTIR), Scanning electron microscopy (SEM) and Thermogravimetric analysis (TGA). Modification of Graphene oxide was confirmed by peak shifting in XRD pattern and new bond attached in FTIR spectra as compared with GO. SEM, TGA and dispersion characterization was done to observe the change in characteristics properties of modified GO. SEM analysis was used to observe the change in morphology of graphene oxide. TGA was used to study the decomposition of the material as a function of temperature. The FGO was completely soluble in methanol, propan-1-ol, DMF, acetone, ethanol and DMSO which shows that FGO have good dispersible properties and may find its application in various fields like gas and humidity sensors.

In this work, with the available solid-liquid equilibrium (SLE) data of six aromatic carboxylic acids, aromatic dicarboxylic acid isomers (terephthalic acid (TPA), isophthalic acid (IPA), and phthalic acid (PA)), and methyl benzoic acid isomers (m-toluic acid (m-TA), o-toluic acid (o-TA), and p-toluic acid (p-TA)) in acetic acid (HOAc) + water (H2O) solvent mixtures, the relationship between the molecular structure of the above aromatic carboxylic acids and the solubility of them in HOAc + H2O solvent mixtures is discussed. It could be found that among the aromatic dicarboxylic acid isomers and methyl benzoic acid isomers, TPA and p-TA have the lowest solubility in the same solvent and temperature, respectively. Meanwhile, three new groups, p-ArCOOH, m-ArCOOH, and o-ArCOOH, in the UNIFAC (Dortmund) model were first defined to distinguish the influence of the positions of ArCOOH on the thermodynamic properties of aromatic carboxylic acid isomers, which indicates that ArCOOH is located in the para, meta, and ortho positions of the ArCOOH or ArCH3 groups, respectively. Then, the interaction parameters of ArCOOH, p-ArCOOH, m-ArCOOH, and o-ArCOOH with other involved groups in the solvent systems are first obtained by regressing these available SLE data. By using the new defined group, the UNIFAC (Dortmund) model was used to correlate SLE data for the above ternary systems, and trimesic acid + HOAc + H2O systems agree with the experimentally measured results satisfactorily.

The transition-metal-catalyzed carboxylation of aryl and vinyl chlorides with CO2 is rarely studied, and has been achieved only with a Ni catalyst or combination of palladium and photoredox. In this work, the cobalt-catalyzed carboxylation of aryl and vinyl chlorides and bromides with CO2 has been developed. These transformations proceed under mild conditions and exhibit a broad substrate scope, affording the corresponding carboxylic acids in good to high yields.

Four Ru(ii)-NC complexes were synthesized by one-step processes from the corresponding NC ligands with RuHCl(CO)(PPh3)(3). These complexes were tested as catalysts for alcohol dehydrogenative reactions, and complex {(C5H4N)-(C6H4)}RuCl(CO)(PPh3)(2) (1) showed the highest activity. With KOH as the nucleophile and 0.5 mol% catalyst loading, a series of carboxylic acids were synthesized in toluene without any oxidant. Catalyst 1 could be transformed to complex {(C5H4N)-(C6H4)}RuH(CO)(PPh3)(2) (6) when treated with KOH and benzyl alcohol. Complex 6 further reacted with PhCHO and H2O to generate product {(C5H4N)-(C6H4)}Ru(OCOPh)(CO)(PPh3)(2) (7). Complexes 6 and 7 exhibited similar efficiency to complex 1, suggesting that they can be regarded as the catalytic intermediates of 1.

Electrospray ionization (ESI) is widely used as an ionization source for the analysis of complex mixtures by mass spectrometry. However, different compounds ionize more or less effectively in the ESI source, meaning instrument responses can vary by orders of magnitude, often in hard-to-predict ways. This precludes the use of ESI for quantitative analysis where authentic standards are not available. Relative ionization efficiency (RIE) scales have been proposed as a route to predict the response of compounds in ESL In this work, a scale of RIEs was constructed for 51 carboxylic acids, spanning a wide range of additional functionalities, to produce a model for predicting the RIE of unknown compounds. While using a limited number of compounds, we explore the usefulness of building a predictor using popular supervised regression techniques, encoding the compounds as combinations of different structural features using a range of common fingerprints. It was found that Bayesian ridge regression gives the best predictive model, encoding compounds using features designed for activity coefficient models. This produced a predictive model with an R-2 score of 0.62 and a root-mean-square error (RMSE) of 0.362. Such scores are comparable to those obtained in previous studies but without the requirement to first measure or predict the physical properties of the compounds, potentially reducing the time required to make predictions.
