Hydrogen peroxide (H2O2) is a small molecule of reactive oxygen species, mainly produced by cell mitochondria, which plays an important role in physiological processes. Excess of H2O2 in normal cells could causes a variety of diseases. For that reason, it is very significant to emerge a detection method with high-precision for H2O2. Herein, we reported a structurally novel fluorescent probe, para-nitrophenyl oxoacetyl rhodamine (RhB-NIR) for the detection of H2O2 levels in living cells. The results show that the Stokes shift for RhB-NIR is 140 nm, much larger than those for other reported rodamine derivatives. RhB-NIR shows satisfactory specificity and high sensitivity for the detection of H2O2. Excellent linear relationship with H2O2 within a certain concentration range (0-10 mu M) was displayed, and the limit of detection (LOD) is 61 nM. More importantly, RhB-NIR realized fluorescence imaging of H2O2 in living cells. In addition, RhB-NIR also shows great potential for targeting mitochondria in cell colocalization experiments, in which the Pearson’s coefficient is 0.91 using Rhodamine 123 as a reference. This probe will be a promising tool for detecting H2O2 in the future research.

A practical method for the oxidation of aromatic side chains was established for the preparation of aromatic aldehydes and ketones. Using NiCl2 as the catalyst, substituted toluenes were oxidized with Na2S2O8 at the benzvlic site for the synthesis of the corresponding aldehydes in the yield of 22%similar to 79%. Ethylbenzene analogs were oxidized more easily to obtain the corresponding ketones with 64%similar to 84% yields. The oxidation of benzyl alcohol analogs was completed to acquire the corresponding carbonyl compounds in shorter time with better selectivity and yields. The method has the advantages such as the mild reaction conditions, no requirement for precious metals or additional promoter, and good selectivity.

A new Au(I)-catalyzed method for the preparation of trisubstituted indolizines from easily accessible 2-propargyloxy-pyridines is reported. The reaction tolerates a wide range of functionality, allowing for diversity to be introduced in four distinct regions of the product (R, R-1, R-2, and Ar). The proposed mechanism proceeds via enol addition to an allenamide intermediate and explains the observed increase in yields when electron poor methyl ketones are utilized.

A new synthesis of 2-aroylbenzothiazoles via iodine-promoted domino transformations of anilines, acetophenones, and elemental sulfur was demonstrated. The highlights of this tandem synthesis are (1) easily available anilines and acetophenones as feedstock; (2) transition metal-free conditions; (3) inexpensive, nontoxic, easy handling, and abundant elemental sulfur as a building block. This synthetic strategy would complement the existing methods in the synthesis of this important heterocyclic scaffold. To our best knowledge, the formation of 2-aroylbenzothiazoles from simple anilines, acetophenones, and elemental sulfur was not previously reported in the literature.

In this work, N-Cbz hydrazone has been employed as a rarely explored directing group for the synthesis of isoquinolines by annulation with internal alkynes via C-H/ N-N activation using Ru catalyst. Additive as well as external oxidant-free rapid protocol has been established for the synthesis of isoquinolines using microwave strategy. Use of non-volatile and biodegradable PEG as a green solvent with lower catalyst loading makes the proposed protocol environmentally benign. Further, higher functional group tolerance and wide substrate scope has been observed under the stated methodology with higher yields.

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).

Magnetic graphene quantum dots were prepared and incorporated in cyclodextrin decorated chitosan. The resulting hybrid was then palladated and characterized using TEM, BET, TGA, XRD, VSM, ICP and FTIR spectroscopy. Next, the catalytic activity of the prepared hybrid catalyst that benefits from the chemistry of both carbohydrates and magnetic graphene quantum dots was investigated for promoting hydrogenation reaction of nitroarenes in aqueous media under mild reaction condition. The study of the catalyst performance confirmed high catalytic activity and selectivity of the catalyst towards hydrogenation of the nitro group. Moreover, the catalyst could be magnetic-ally separated from the reaction mixture and recycled up to ten reaction runs with a slight loss of the catalytic activity and Pd leaching.These results showed that the hybrid of magnetic graphene quantum dots and carbohydrates is an efficient catalyst support that can be potentially applied for the immobilization of nanoparticles to furnish heterogeneous catalysts for promoting the chemical transformations.

Name: 1-(4-Nitrophenyl)ethanone. I found the field of Chemistry very interesting. Saw the article Structural and femtosecond third-order nonlinear optical properties of electron donor- acceptor substituted chalcones: An experimental and computational approach published in 2020.0, Reprint Addresses Patil, PS (corresponding author), KLE Inst Technol, Dept Phys, Hubballi 580030, Karnataka, India.. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone.

Structural and third-order nonlinear optical (NLO) properties of two D-pi-A-pi-A [(2E)-3-(3-chlorophenyl)-1-(3-nitrophenyl)prop-2-en-1-one (3C3NC) and (2E)-3-(4-fluorophenyl)-1-(4-nitrophe nyl)prop-2-en-1-one (FNC)] and one D-pi-A-pi-D [(2E)-1-(9-anthryl)-3-(4-fluorophenyl) prop-2-en-1-one (FANC)] type chalcone derivatives were investigated experimentally as well as theoretically. All the three chalcones are centrosymmetric (CS) and crystallized in P2(1)/c space group. In crystal packing, all compounds exhibit CeH center dot center dot center dot O hydrogen bonds and pi center dot center dot center dot pi interactions. From UV-Vis-NIR absorption spectra, the cut-off wavelength and optical band gaps of the chalcones were evaluated. The thermal stability and the melting point of the chalcones were determined from the TGA/DTA techniques. The ultrafast third-order NLO properties of the three chalcones in solution (0.01 M) were evaluated by Z-scan technique using femtosecond (fs) pulses from Ti: Sapphire laser (similar to 150 fs, 80 MHz, 800 nm). Third-order nonlinear absorption (NLA) coefficient (beta similar to 10(-9) cmW(-1)), nonlinear refraction (NLR) index (n(2)similar to 10(-14) cm(2)W(-1)), susceptibility (chi((3)) similar to 10(-12) esu) and molecular hyperpolarizability (gamma(h) similar to 10(-31) esu) were unambiguously determined. The chalcones satisfy the condition to observe reverse saturable absorption (RSA) mechanism (sigma(ex) > sigma(g)). Further, the larger values of sigma(ex)/sigma(g) (similar to 2-3) indicate that the chalcones would exhibit remarkable optical limiting property. The estimated optical limiting (OL) threshold values are in the order of mu J/cm(2). Further, all the chalcones have satisfied the one-photon and two-photon figures of merit conditions (W > 1 and T < 1) for the optical switching applications. In addition to experimental findings, the optimized geometry, HOMO-LUMO energy gap, NLO parameters such as electronic dipole moment, polarizability, first and second hyperpolarizabilities of all the three chalcones were determined theoretically (DFT) for different wavelength at B3LYP/6-311 thorn G (d,p) basic set. The experimentally determined second-order susceptibilities (Z-scan technique) are reasonably in agreement with the computational values (TD-DFT). The MEP surface revealed that the 3C3NC, FNC and FANC molecules have some potential sites for electrophilic and nucleophilic attack. The experimental and computational NLO data clearly suggest that the nonlinearity of chalcone molecules greatly depends on the electron donor and acceptor strengths of the substituents. Further, all the chalcones are potential materials for optical limiting and optical switching applications. (C) 2020 Elsevier B.V. All rights reserved. Name: 1-(4-Nitrophenyl)ethanone.
