I found the field of Chemistry very interesting. Saw the article Catalytic C-H aerobic and oxidant-induced oxidation of alkylbenzenes (including toluene derivatives) over VO2+ immobilized on core-shell Fe3O4@SiO2 at room temperature in water published in 2020.0.

Direct C-H bond oxidation of organic materials, and producing the necessary oxygenated compounds under mild conditions, has attracted increasing interest. The selective oxidation of various alkylbenzenes was carried out by means of a new catalyst containing VO2+ species supported on silica-coated Fe3O4 nanoparticles usingt-butyl hydroperoxide as an oxidant at room temperature in H2O or solvent-free media. The chemical and structural characterization of the catalyst using several methods such as FTIR spectroscopy, XRD, FETEM, FESEM, SAED, EDX and XPS showed that VO2+ is covalently bonded to the silica surface. High selectivity and excellent conversion of various toluene derivatives, with less reactive aliphatic (sp(3)) C-H bonds, to related benzoic acids were quite noticeable. The aerobic oxygenation reaction of these alkylbenzenes was studied under the same conditions. All the results accompanied by sustainability of the inexpensive and simple magnetically separable heterogeneous catalyst proved the important criteria for commercial applications.

I found the field of Chemistry very interesting. Saw the article Effective and selective direct aminoformylation of nitroarenes utilizing palladium nanoparticles assisted by fibrous-structured silica nanospheres published in 2020.

Palladium nanoparticles (similar to 1-3 nm, 0.4 wt% Pd) were uniformly distributed over the surface of fibrous silica nanospheres (KCC-1) modified via aminopropyltriethoxysilane using a fast and cost-effective palladium (II) chloride reduction process. The Pd nanoparticles (Pd NPs) distribution over the ensuing catalyst Pd/KCC-1-NH2 showed much more uniform distribution, and smaller size compared with the tedious hydrothermal reduction method. The morphological, chemical, and size analyses of Pd/KCC-1-NH2 by BET, UV-Vis spectra, XRD, HR-TEM, EDS and XPS analysis revealed that the succeeding material consist of a distinct fibrous silica nanospheres support adorn with Pd NPs. The resultant nanocatalyst was tested for the one-step reductive aminoformylation of aromatic nitro compounds using formic acid. A wide range of substituted nitroarenes including electron withdrawing, releasing, sterically hindered and multifunctional groups have been converted to corresponding aryl formamide in quantitative yields (yields up to 98%) at moderate temperature (70 degrees C). Optimization study has proved that the 6 equivalent of formic acid is required and toluene was found to be the better solvent. The established practice is beneficial due to the use of formic acid as H-2 source and formylating agent, easiness in handling of the catalyst and simple workup procedure with efficient catalyst reusability.

A rhodium catalyzed copper mediated double oxidative annulation of propargylamino phenyl benzamides is developed. A quick assembly of tri, tetra and penta cyclic pyrido/isoquinolo-quinoxilines are thus achieved from readily available linear substrates. The reaction is shown to be very general by accommodating a large variety of substrates in the transformation. A mechanism through an amide directed C-H bond activation followed by an intramolecular alkyne activation/annulation followed by an oxidation is postulated.

This paper emphasizes the preparation of nonlinear optical (NLO) responsive chromophores and their corresponding polymers. Initially, the carboxyl acid group-based precursors of the chromophores containing strong acceptors such as nitro-substituted thiazole and thiadiazole groups were prepared and subjected to condensation reactions with a monomer to yield a series of polymers. Prior to the synthesis of the polymers, a thermally crosslinkable monomer, 2,6-di-(octy-1-nyl)-p-phenylenediamine, was synthesized by a Sonogashira coupling reaction. All the synthesized precursors, the monomer and their corresponding polymers were characterized using FTIR, H-1 NMR, and CHN analyses and UV-Vis spectrophotometry. Simultaneously, the molecular structures of the precursors were designed and optimized using the Gaussian 16 (Revision A.03) program. The dipole moments, energy band gaps between the HOMO and LUMO, polarizabilities and first order hyperpolarizabilities of the precursors were calculated theoretically using the DFT approach; the values were in the ranges of 9.4321-15.3354 D, 1.3709-1.4146 eV, 53.40-64.80 x 10(-24) esu and 3703.35-5254.90 x 10(-32) esu, respectively. The inherent viscosities (eta inh) of the polymers were measured by an Ubbelohde viscometer and were in the range of 0.2453-0.2860 dl g(-1). The thermal behavior of the polymers was investigated using DSC and TGA. The glass transition temperatures of the polymers were in the range of 190-218 degrees C. The thicknesses and refractive indices of the thin films were determined by ellipsometry, and the values were in the range of 0.100-0.127 mu m and 1.211-1.426, respectively. The molecular orientations in the thin polymer films were induced by corona poling and were ascertained using both a UV-Vis spectrophotometer and an atomic force microscope. The second harmonic generations (SHGs) of the poled polymers were determined using an Nd-YAG laser. The SHG coefficients (d(33)) ranged between 98.30 and 106.04 pm V-1 at 532 nm. Among the synthesized polymers, the polymer containing dinitro-substituted thiazole demonstrated an excellent SHG coefficient as high as 106.04 pm V-1. Furthermore, none of the polymers showed SHG decay below 100 degrees C, and they retained 95% of their SHG values even up to 600 h. Based on its enhanced NLO efficiency and long temporal stability, the polymer containing dinitro-substituted thiazole can be a particularly promising candidate for photonic devices.

Herein we report, a single-pot multistep conversion of inactivated carboxylic acids to various N-containing compounds using a common synthetic methodology. The developed methodology rendered the use of carboxylic acids as a direct surrogate of primary amines, for the synthesis of primary ureas, secondary/tertiary ureas, O/S-carbamates, benzoyl ureas, amides, and N-formyls, exploiting the Curtius reaction. This approach has a potential to provide a diversified library of N-containing compounds, starting from a single carboxylic acid, based on the selection of the nucleophile.

Presented herein are the Al(III)molecular ring architectures from 8-ring to 16-ring. Although there are numerous reported cyclic coordination compounds based on transition metals, gallium, or lanthanides, the Al versions are less developed due to the fast hydrolysis nature of Al(3+)ion. With the assistant of monohydric alcohols, a series of atomic precisely Al molecular rings based on benzoates are synthesized. The ring expansion of these Al-rings from 8-ring to 16-ring is related to the monohydric alcohol structure-directing agents. Moreover, the organic ligands on the Al-rings can be modified by using various benzoate derivatives, which lead to tunable surface properties of the Al-rings from hydrophilicity to ultra-hydrophobicity. Importantly, 4-aminobenzoic acid bridged 16-ring is soluble in organic solvents and exhibits high solution stability revealed by mass spectroscopy. Ligand substitution also can be performed between these Al-rings, which reveal controllable ligand functionalization of these Al-rings.

Highly sensitive and selective detection of nitro containing high energy organic compounds such as picric acid (PA), 2,4,6-trinitrotoluene (TNT) and 2,4-dinitrotoluene (DNT) has become a challenging task due to concerns over national security, criminal investigations and environment protections. Among various known detection methods, fluorescence sensors have gained special attention in recent time. The family of fluorescent sensors based on push-pull systems that incorporate nitrogen heterocycles as an electron-withdrawing group have a growing interest due to their high sensitivity, selectivity and easy tuning. The fluorescent sensors discussed in this review are classified and organized according to used azahetemcyclic scaffold, their functionality and their ability to detect of nitmaromatics by fluorescence quenching.
