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.

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.

Product Details of 93-02-7. I found the field of Chemistry very interesting. Saw the article Experimental and theoretical investigations of novel synthesized organo-silane compounds and modified mesoporous silica materials published in 2019.0, Reprint Addresses Ermis, E (corresponding author), Eskisehir Tecn Univ, Fac Sci, Dept Chem, TR-26470 Eskisehir, Turkey.. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde.

In this study, the novel compounds (2,5-dimethoxy-methanimine propyltriethoxysilane; S1 and 3-ethoxy-salicylaldimine propyltriethoxysilane; S2) derived from aminopropyltriethoxysilane (APTES) were synthesized by a simple and facile approach in order to modify mesoporous silica (MS) surface. Characterization of S1 and S2 was experimentally performed by FTIR, H-1-C-13 NMR spectroscopic methods and elemental analysis. The IR frequencies, H-1 and C-13 NMR chemical shift values for the optimized molecular geometries of S1 and S2 were calculated by using Density Functional Theory (DFT with B3LYP/6-311 + G (d, p) basis set), and the theoretical results were compared to the obtained experimental data. The experimental and theoretical results confirmed the proposed molecular structures of the synthesized S1 and S2 compounds. After that, the mesoporous silica material (MS) was synthesized according to the Stober procedure, and characterized by the elemental analysis, and the experimental and theoretical IR spectra. The surface of MS was successfully functionalized with S1 and S2 to produce more selective and effective adsorbent materials, and the structures of functionalized MSs (S1-MS and S2-MS) were investigated with FTIR spectroscopy and elemental analysis. The theoretical optimized molecular geometries, IR frequencies and H-1-C-13 NMR chemical shift values were calculated to execute the structural analysis of S1-MS and S2-MS. In addition, the calculations of the sum of electronic and thermal free energy (SETFE), dipole moment, the HOMO-LUMO energies, the molecular electrostatic potential (MEP), the solvent accessible surface (SAS) and atomic charge for the synthesized S1, S2, MS, S1-MS and S2-MS were accomplished by using DFT/B3LYP/6-311 + G (d, p) level of theory.

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.

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

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.

A novel Pt(II) complex of [Pt-II(MPP)(OPD)]Cl center dot H2O (MPP-Pt) (OPD = o-phenylenediamine) with 2-(2,5-methoxy-phenyl) imidazo [4,5-f]-[1, 10] phenanthrolin (H-MPP) was synthesized and fully characterized. In MPP-Pt complex, the Pt(II) ion adopts a four-coordinated square planar geometry. MPP-Pt exhibited selective cytotoxicity against human carcinoma (A549), hepatoblastoma (Hep-G2), ovarian (SK-OV-3), cervical (HeLa) and gastric adenocarcinoma (MGC80-3) cell lines with IC50 values in the micromolar range (0.31-9.48 mu M), but low cytotoxicity toward HL-7702 normal cells. Various experiments showed that MPP-Pt complex caused cell apoptosis via mitochondrial dysfunction in HeLa cells, as shown by the up-regulation expression of p27, apaf-1, p21, cytochrome c (cyc c) and p53 levels, loss of mitochondrial membrane potential (MMP) and the down-regulation expression of bcl-2 protein level.

A new series of pyrido[2,3-d] pyrimidines 3-18 bearing substitution at C-5 position was synthesized. All compounds were tested for their in vitro antitumor activity against five human cancer cell lines namely; hepatocellular carcinoma (HePG2), breast carcinoma (MCF-7), human prostate carcinoma (PC3), colorectal carcinoma (HCT-116), and cervical carcinoma (Hela) using doxorubicin as a positive control. Compounds 3, 4, 9, 11, 13, 14, 15 and 17 exhibited the highest antitumor activity against the tested cell lines and were selected to screen their enzymatic inhibition against dihydrofolate reductase enzyme (DHFR) compared with the reference drug methotrexate (MTX), to explain the probable mechanism of action of the observed anticancer activity. Compound 11 displayed the highest inhibitory activity (IC50 = 6.5 mu M) among the tested compounds in comparison with MTX (IC50 = 5.57 mu M). Also, compounds 13 and 14 showed high inhibitory activity against DHFR with IC50 values 7.1 and 8.7 mu M, respectively. Comparative molecular modeling study was performed between DHFR inhibitors 11, 13 and 14 of the highest activity and 10 of the lowest activity among the eight inhibitors against MTX. Docking studies into the active site of DHFR domain showed good agreement with the obtained biological results. Finally, compound 11 was found to be best antitumor, DHFR inhibitor, and it induced the process of apoptosis at Pre-G phase and cell cycle arrest at G2/M phase in MCF-7 cells.

Sodium is the most abundant alkali metal in the Earth’s crust and the ocean. However, organosodium compounds have long been considered inferior to organolithium compounds, which have instead dominated synthetic organic chemistry during the last century. Despite being largely neglected because of their reactive nature, it is worth re-exploring organosodium chemistry, in light of the growing demand for sustainable syntheses without recourse to less abundant elements such as lithium. Herein, we demonstrate that, contrary to common belief, organosodium compounds can be easily prepared from aryl chlorides or (hetero) arenes and easy-to-handle sodium dispersion and, after being transmetallated to the corresponding zinc and boron compounds, they readily participate in the Negishi and Suzuki-Miyaura cross-coupling reactions, fundamental carbon-carbon bond-forming reactions in organic synthesis. Direct coupling reactions with organosodium species were also possible.
