Direct C-S bond coupling is an attractive way to construct aryl sulfur ether, a building block for a variety of biological active molecules. Herein, we disclose an effective model for regioselective thiolation of the aromatic C-H bond by thiol activation instead of arene activation. Strikingly, this method has been applied into anisole derivatives that are not available in the arene activation approach to forge a single thioether isomer with high reactivity.

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.

A facile synthesis of isocoumarin and alpha-pyrones derivatives by Ru(II)-catalyzed oxidative annulation of aromatic acids and alkynes is reported. This reaction could undergo smoothly in water by use of air as the sole oxidant and accomplishes with the tolerance of a wide range of functional groups. Additionally, the oxidative cyclization of benzoic acid and acrylate is also achieved in the same conditions to furnish the isobenzofuran-1(3H)-one scaffold.

Through topology-guided synthesis, a Zr-based mesoporous MOF was successfully constructed, adopting a b-cristobalite-type structure. The MOF is embedded with well-arranged terpyridine coordination sites for facile post-syntheticmetalation, and can be effectively used as a general scaffold for the preparation of noble-metal-free catalysts. For instance, the scaffolded metal@MOF material exhibits highly efficient catalytic activity for alkene epoxidation and arene borylation.

Our group recently reported the use of [(DPEPhos)(bcp)Cu]PF6 as a general copper-based photoredox catalyst which proved efficient to promote the activation of a broad variety of organic halides, including unactivated ones. These can then participate in various radical transformations such as reduction and cyclization reactions, as well as in the direct arylation of several (hetero)arenes. These transformations provide a straightforward access to a range of small molecules of interest in synthetic chemistry, as well as to biologically active natural products. Altogether, [(DPEPhos)(bcp)Cu]PF6 acts as a convenient photoredox catalyst which appears to be an attractive, cheap and complementary alternative to the state-of-the-art iridium- and ruthenium-based photoredox catalysts. Here, we report a detailed protocol for the synthesis of [(DPEPhos)(bcp)Cu]PF6, as well as NMR and spectroscopic characterizations, and we illustrate its use in synthetic chemistry for the direct arylation of (hetero)arenes and radical cyclization of organic halides. In particular, the direct arylation of N-methylpyrrole with 4-iodobenzonitrile to afford 4-(1-methyl-1H-pyrrol-2-yl)benzonitrile and the radical cyclization of N-benzoyl-N-[(2-iodoquinolin-3-yl)methyl]cyanamide to afford natural product luotonin A are detailed. The scope and limitations of this copper-based photoredox catalyst are also briefly discussed.

Molecular acidity is an important physicochemical property, which is often represented by the pK(a) value as the measure of acidity strength. However, the accurate calculation and prediction of pK(a) values is still an unsolved problem for computational chemistry. In this work, we present for the first time a direct correlation between pK(a) values and local vibrational frequencies for 15 different groups of compounds with various substituents. This correlation was derived from a quadratic function of two selected local vibrational frequencies as independent variables used to characterize electronic structure features influencing the molecular acidity. In total, 180 molecules were investigated with this correlation model. For each group of molecules, we found a strong correlation with root mean squared errors and mean absolute errors of less than 0.11 and 0.09 pK(a) units, respectively. The correlation between pK(a) and local vibrational modes, established in this work, can be generally applied to all compounds whose pK(a) values are dominated by electronic substituent effects. In this regard, the new correlation model constitutes a powerful link between the well-known Hammett equation and vibrational spectroscopy. Furthermore, it allows a quick prediction of the pK(a) values for new group members with different substituents.

The chemical composition of essential oils (EOs) isolated by hydrodistillation from Pterocarpus soyauxii Taub. root wood and root bark were determined for the first time by GC/MS analysis. The EOs gave a percentage yield (w/w) of 0.34 % and 0.31 % for root wood and root bark respectively. A total of 60 compounds accounting for 86.1 % of the root wood EO composition were identified with monoterpenes (45.4 %) and sesquiterpenes (14.7 %) as predominant constituents. Root bark EO gave 53 identified constituents which make up about 78.5 % of the EO dominated by non-terpenes (23.4 %) and alkanes (14.1 %). The EOs are good sources of limonene (16.9 %), gamma-terpinene (9.8 %) and p-cymene (6.70 %). The anti-diabetic (alpha-amylase and alpha-glucosidase models) and antioxidant activities (DPPH and H2O2 models) of EOs were evaluated in comparison with standard drugs. Alpha-amylase inhibition gave IC50 values (mg/mL) of 0.0493 and 0.0471 for root wood and root bark EOs respectively, compared to acarbose the standard anti-diabetic drug (0.0401) while alpha-glucosidase assay gave IC50 values (mg/mL) of 0.0517 and 0.0486 for root wood and root bark EOs respectively, compared with acarbose (0.0418). In the DPPH antioxidant assay, root bark EO showed higher activity (0.157 mg/mL) compared to root wood EO (0.159 mg/mL) while Root wood and root bark EOs had IC(50 )values (mg/mL) of 0.157 and 0.171 respectively using the H2O2 model. Results revealed the presence of chemical constituents in the EOs which could be responsible for activities expressed by the plant.

A nickel-catalyzed aryl-aroyloxyl C(sp(2))-O radical cross-coupling reaction conducted using a redox active ester with aryl zinc reagent was developed. This method demonstrates a new disconnection approach for formation of aryl aryl esters. In the one-pot sequential process, the readily available aryl carboxylic acids can be converted into functionalized aryl aryl esters and heteroaryl esters. This protocol is amenable to the gram-scale synthesis. The present method has a wide substrate scope and high functional group tolerance.
