As a key element in the construction of complex organic scaffolds, the formation of C-C bonds remains a challenge in the field of synthetic organic chemistry. Recent advancements in single-electron chemistry have enabled new methods for the formation of various C-C bonds. Disclosed herein is the development of a novel single-electron reduction of acyl azoliums for the formation of ketones from carboxylic acids. Facile construction of the acyl azolium in situ followed by a radical-radical coupling was made possible merging N-heterocyclic carbene (NHC) and photoredox catalysis. The utility of this protocol in synthesis was showcased in the late-stage functionalization of a variety of pharmaceutical compounds. Preliminary investigations using chiral NHCs demonstrate that enantioselectivity can be achieved, showcasing the advantages of this protocol over alternative methodologies.

Systematic investigations of a Pd(II)-catalyzed, 8-aminoquinoline directing group (DG)-aided sp(2) delta-C-H amidation (C-N bond formation) of different biaryl carboxamides are reported. Various biaryl carboxamides with suitably positioned sp(2) delta-C-H bond with respect to the DG were assembled via beta-C-H arylation and then they were subjected to Pd(II)-catalyzed sp(2) delta-C-H intramolecular amidation/annulation reactions. While the intramolecular amidation of the sp(2) delta-C-H bond of some carboxamides was not fruitful, several biaryl carboxamides underwent intramolecular amidation of their sp(2) delta-C-H bonds to afford various tricyclic quinolone motifs such as, phenanthridin-6(5H)-ones and thieno-/furo-/pyrrolo-[2,3-c]quinolin-4(5H)-ones. The assembly of the required biaryl carboxamides possessing the sp(2) delta-C-H bond via the beta-C-H arylation and the successive intramolecular amidation (C-N bond formation) of the resulting biaryl carboxamides were also performed in one-pot reaction conditions to afford tricyclic quinolones.

Aqueous complexation of uranyl(VI) ions with methoxy- and methylbenzoates in 0.1 M NaClO4 solutions was studied by means of UV-vis absorption and Raman spectroscopy. The predominance of 1:1 complexation (uranyl to ligand) was verified for all uranyl carboxylates under acidic conditions (-log [H+] < 3.2), and absorption spectra, stability constants, and symmetric stretching frequencies of the uranyl group of the complexes were determined for the first time. For meta- and parasubstituted benzoates, a linear free energy relationship (LFER) was observed between the equilibrium constants for the protonation (log beta(p)) and uranyl complexation (log beta(U)) reactions, and the electronic effects of the substituents were successfully described by the Hammett equation. In the case of ortho-substituted benzoates, the stability constant of uranyl 2-methoxybenzoate is slightly lower than the LFER trend, which is generally explained by the destabilization of cross-conjugation in the uranyl complex due to the steric hindrance between the reaction center and adjacent methoxy group. On the contrary, the stability constant of uranyl 2-methylbenzoate is comparable to the LFER trend, implying that the steric effect is relatively insignificant for the smaller methyl group. The utility of such thermodynamic correlations between the uranyl-substituted benzoates is useful for the molecular understanding and predictive modeling of chemical interactions between actinyl(VI) ions and various organic carboxyl groups.

An iridium-catalyzed selectiveortho-monoiodination of benzoic acids with two equivalent C-H bonds is presented. A wide range of electron-rich and electron-poor substrates undergo the reaction under mild conditions, with >20:1 mono/di selectivity. Importantly, the C-H iodination occurs selectivelyorthoto the carboxylic acid moiety in substrates bearing competing coordinating directing groups. The reaction is performed at room temperature and no inert atmosphere or exclusion of moisture is required. Mechanistic investigations revealed a substrate-dependent reversible C-H activation/protodemetalation step, a substrate-dependent turnover-limiting step, and the crucial role of the Ag(I)additive in the deactivation of the iodination product towards further reaction.

The aquatic ecosystems are dynamic environments often affected directly or indirectly by a myriad of anthropogenic contaminants that need to be properly identified. In this study, liquid chromatography-quadrupole time-of-flight mass spectrometry (LC-QqTOF-MS) suspected-screening was applied to mussels and riverine sediment both, non-spiked and spiked with a mixture of 32 pharmaceuticals. Three data acquisition methods -sequential window acquisition of all theoretical fragment-ion spectra (SWATH), in fix (FSWATH) and variable (VSWATH) window modes and Information Dependent Acquisition (IDA)- were compared to determine the most suitable acquisition technique. The results obtained in the spiked samples showed that the two SWATH modes enable to obtain the MS/MS spectrum of a higher number of compounds (up to 27 with FSWATH and 25 with VSWATH) than IDA (up to 19) in sediment and mussel. The different data acquisition modes were also tested in non-spiked samples to verify the results obtained in the spiked ones. Importantly, all the methods are able to detect the MS/MS spectrum of several contaminants in the samples when analysed against a database of >600 compounds. Up to 7 contaminants were tentatively detected with IDA, 15 with FSWATH and 17 with VSWATH. Most pollutants were pesticides and pharmaceuticals, being of particular interest the presence of ibuprofen and acetaminophen in mussels. (C) 2019 Elsevier B.V. All rights reserved.

The Name is 3-Methylbenzoic acid. Through research, I have a further understanding and discovery of 99-04-7.

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.

Benzotriazoles (4-6) were synthesized which were further reacted with different substituted benzoic acids and phenacyl bromides to synthesize benzotriazole derivatives (7-40). The synthetic compounds (7-40) were characterized via different spectroscopic techniques including EI-MS, HREI-MS, H-1-, and C-13 NMR. These molecules were examined for their anti-hyperglycemic potential hence were evaluated for alpha-glucosidase and alpha-amylase inhibitory activities. All benzotriazoles displayed moderate to good inhibitory activity in the range of IC50 values of 2.00-5.6 and 2.04-5.72 mu M against alpha-glucosidase and alpha-amylase enzymes, respectively. The synthetic compounds were divided into two categories A and B, in order to understand the structure-activity relationship. Compounds 25 (IC50 = 2.41 +/- 131 mu M), (IC50 = 2.5 +/- 1.21 mu M), 36 (IC50= 2.12 +/- 1.35 M), (IC50 = 2.21 +/- 1.08 mu M), and 37 (IC50 = 2.00 +/- 1.22 mu M), (IC50 = 2.04 +/- 1.4 mu M) with chloro substitution/s at aryl ring were found to be most active against alpha-glucosidase and alpha-amylase enzymes. Molecular docking studies on all compounds were performed which revealed that chloro substitutions are playing a pivotal role in the binding interactions. The enzyme inhibition mode was also studied and the kinetic studies revealed that the synthetic molecules have shown competitive mode of inhibition against alpha-amylase and non-competitive mode of inhibition against alpha-glucosidase enzyme.

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.
