A water-mediated MCR strategy has been developed for the synthesis of donor (D)-acceptor(A) type hydrazinyl thiazolyl coumarins (HTCs) (4) in excellent isolated yields (90-98%) from a three component reaction of aromatic aldehydes/ketones (1), thiosemicarbazide (2) and 3-(2-bromoacetyl)-2H-chromen-2-one (3) catalyzed by an environmentally compatible montmorillonite (MMT) K10 clay at RT for 20-40 min. The present MCR strategy has several advantages that include its wide-spread substrate scope, eco-compatibility, short reaction times and products that do not require chromatographic purification. Besides, the method is simple to perform, it is easy to construct C-N, C=N and C-S bonds in one pot and the reaction can be scaled up to a gram level. Moreover, the catalyst can be reused 7 times without significant change of activity. The photophysical properties of the synthesized D-A type HTCs are also studied and it was noticed that the fluorescence properties can be varied with the position of electron donating group on the aromatic ring of aldehyde/ketone of HTCs. Most of the compounds exhibited bright fluorescence in chloroform (1.0 x 10(-5) M) with emission maxima ranging from 409 to 511 nm and large Stokes shifts. Further, the HOMO and LUMO energy levels of the HTCs are found in the range from -5.65 eV to -5.22 eV and -2.67 eV to -2.17 eV, respectively, and in good agreement with the reported hole transporting materials.

Herein we report the generation of benzylic lithiums via an iodine-lithium exchange reaction on benzylic iodides performed in continuous flow using tBuLi as the exchange reagent. The resulting benzylic lithium species are trapped in situ by carbonyl electrophiles under Barbier conditions, resulting in benzylic secondary and tertiary alcohols. This flow procedure further allows the generation of highly reactive heterobenzylic lithium compounds, which are difficult to generate under batch conditions. A general scale-up was possible without further optimization.

The conversion of aldehydes and ketones to 1 degrees amines could be promoted by half-sandwich iridium complexes using ammonium formate as both the nitrogen and hydride source. To optimize this method for green chemical synthesis, we tested various carbonyl substrates in common polar solvents at physiological temperature (37 degrees C) and ambient pressure. We found that in methanol, excellent selectivity for the amine over alcohol/amide products could be achieved for a broad assortment of carbonyl-containing compounds. In aqueous media, selective reduction of carbonyls to 1 degrees amines was achieved in the absence of acids. Unfortunately, at Ir catalyst concentrations of <1 mM in water, reductive amination efficiency dropped significantly, which suggest that this catalytic methodology might be not suitable for aqueous applications where very low catalyst concentration is required (e.g., inside living cells).

Safety of 4′-Hydroxyacetophenone. I found the field of Chemistry; Physics very interesting. Saw the article Unveiled understanding on corrosion inhibition mechanisms of hydrazone derivatives based on naproxen for mild steel in HCl: A joint experimental/theoretical study published in 2020.0, Reprint Addresses Lgaz, H; Chung, IM (corresponding author), Kirkuk Univ, Coll Educ, Dept Chem, Kirkuk, Iraq.. The CAS is 99-93-4. Through research, I have a further understanding and discovery of 4′-Hydroxyacetophenone.

The current investigation seeks to explore the adsorption mechanism of newly synthesized Naproxen-based hydrazones on mild steel (MS) surface in 1.0 M HCI solution and their corrosion inhibition efficiencies. To this end, two hydrazone derivatives namely, (E)-N’-(1-(4-chlorophenypethylidene)-2-(6-methoxynaphthalen-2-yl)propanehydrazide (PHD-Cl) and (E)-N’-(1-(4-hydroxyphenypethylidene)-2-(6-methoxynaphthalen-2-yl) propanehydrazide (PHD-OH) were synthesized, characterized and their corrosion inhibition effects were evaluated using a combined electrochemical and theoretical approach. It is evidently dear from the findings presented in this investigation that the two inhibitors exhibited excellent protection efficiency, and the best inhibition performance was shown by PHD-OH inhibitor (96% at 5 x 10(-3) M ). Weight loss measurements revealed that the optimum concentration of inhibitors is 5 x 10(-3) mol/L. The experimental results obtained by electrochemical techniques (potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS)) indicated that the presence of PHD-CI and PHD-OH compounds greatly increased the polarization resistance and affected both anodic and cathodic reactions, i.e. mixed-type inhibitors. Based on electrochemical results, the polarization resistance was greatly increased, from an initial value for the MS (in 1.0 moll HCI) of 29 up to 871 Omega cm(2) for the inhibited solution (1.0 mol/L HCl with 5 x 10(-3) mol/L. of PHD-OH). Furthermore, the adsorption isotherm coincides well with the Langmuir isotherm model. The effect of temperature on PHD-OH adsorption was investigated, experimentally using weight loss tests, and theoretically using molecular dynamic simulations (MD). Moreover, the study found that a protective barrier was set up through the adsorption of the studied compounds on MS surface which is confirmed by scanning electron microscopy with energy-dispersive X-ray analysis (SEM-EDX). Moreover, molecular proprieties of corrosion inhibitor molecules were explored from a theoretical viewpoint using Density Functional Theory (DFT), molecular dynamic (MD) simulation and radial distribution function (RDF) studies. Theoretical results that were in good agreement with experimental findings demonstrated strong interactions between inhibitor molecules and metal surface. (C) 2020 Elsevier B.V. All rights reserved.

The regio- and diastereoselective synthesis of oxazolidinones via a Pd-catalyzed vicinal C-N/C-Cl bond-forming reaction from internal alkenes of allylic carbamates is reported. The oxazolidinones are obtained in yields of 44 to 95% with high to excellent diastereoselectivities (from 6 : 1 to >20 : 1 dr) from readily available precursors. This process is scalable, and the products are suitable for the synthesis of useful amino alcohols. A detailed theoretical and experimental mechanistic study was carried out to describe that the reaction proceeds through an anti-aminopalladation of the alkene followed by an oxidative C-Pd(ii) cleavage with retention of the carbon stereochemistry to yield the major diastereomer. The role of Cu(ii) in a C-Cl bond-forming mechanism step has also been proposed.

The synthesized MgTi2O4.TiO2.Zn2TiO4 nanomaterial was characterized by XRD (X-Ray diffraction), SEM (Scanning electron microscopy), EDS (Energy dispersive x-ray spectroscopy), FTIR (Fourier transform infrared spectroscopy) and PL (Photoluminescence) study. Particles size of MgTi2O4.TiO2.Zn2TiO4 nanomaterial was found to be 37.3 nm. PL and PLE (Photoluminescence excitation) spectra are showed several peaks including one red PL at 723 nm, when excited at 320 nm. Nanomaterial was subject to electrochemical sensor study. Thin layer of synthesized MgTi2O4.TiO2.Zn2TiO4 nanomaterials was fabricated onto the glassy carbon electrode (GCE) with conducting binder to result the working electrode of 4-nitrophenylhydrazine (4-NPHyd) sensor, which was applied successively to selectively detect the 4-NPHyd in aqueous phase. The 4-NPHyd chemical sensor exhibited high sensitivity with lower detection limit, long-term stability in chemical environment and improved electrochemical responses during sensing performance. The linearity of calibration plot is obtained over the large linear dynamic range (LDR) from 0.1 nM to 0.1 mM of 4-NPHyd. The sensitivity calculated from the slop of calibration plot (ratio of current to concentration of 4-NPHyd) is 42.7215 mu AmM(-1)cm(-2) with detection limit (DL) of 0.02 +/- 0.001 nM at signal to noise ratio of 3(S/N). Therefore, the chemical sensor based on MgTi2O4.TiO2.Zn2TiO4 nanomaterials may be a promising highly sensitive sensor in electrochemical method for the effective detection of hazardous and carcinogenic chemicals in medical as well as biological sectors.

The B3NO2 six-membered heterocycle (1,3-dioxa-5-aza-2,4,6-triborinane = DATB), comprising three different non-carbon period 2 elements, has been recently demonstrated to be a powerful catalyst for dehydrative condensation of carboxylic acids and amines. The tedious synthesis of DATB, however, has significantly diminished its utility as a catalyst, and thus the inherent chemical properties of the ring system have remained virtually unexplored. Here, a general and facile synthetic strategy that harnesses a pyrimidine-containing scaffold for the reliable installation of boron atoms is disclosed, giving rise to a series of Pym-DATBs from inexpensive materials in a modular fashion. The identification of a soluble Pym-DATB derivative allowed for the investigation of the dynamic nature of the B3NO2 ring system, revealing differential ring-closing and -opening behaviors depending on the medium. Readily accessible Pym-DATBs proved their utility as efficient catalysts for dehydrative amidation with broad substrate scope and functional-group tolerance, offering a general and practical catalytic alternative to reagent-driven amidation.

Metal-organic frameworks (MOFs) show promise for catalysis applications due to their porosity, high internal surface area, and structural adaptability. Typical acetylation reactions of aldehydes require elevated temperatures and excess alcohol to drive the reactions to completion. In this current work, MOF-808 is used as a heterogeneous catalyst for acetylation of aldehydes in methanol using a mild photothermal process. Optimized conditions gave 72% yield of 2-(dimethoxymethyl)naphthalene in the presence of 10 mol% MOF-808 at 45 degrees C using only a fluorescent lamp. MOF-808 can be recycled up to 5 times with no loss in catalytic activity. A proof-of-principle substrate scope demonstrates the potential utility for aromatic and aliphatic substrates.
