Safety of Benzophenone. In 2021.0 POLYMERS-BASEL published article about POLYMERS; KINETICS; DYES in [Huang, Tung-Liang; Chen, Yung-Chung] Natl Kaohsiung Univ Sci & Technol, Dept Chem & Mat Engn, Kaohsiung 80778, Taiwan; [Chen, Yung-Chung] Natl Kaohsiung Univ Sci & Technol, Photo SMART Photo Sensit Mat Adv Res & Technol Ct, Kaohsiung 80778, Taiwan in 2021.0, Cited 31.0. The Name is Benzophenone. Through research, I have a further understanding and discovery of 119-61-9.

Three novel visible-light absorbing benzophenone-based hydrogen acceptors (BPD-D, BPDM-D and BPDP-D) were designed on the basis of a donor-benzophenone-donor structural backbone. Mono or diketone units and double diphenylamine electron-donating groups in para-or meta-positions were introduced to comprehend the electronic and structural effects on free radical photopolymerization (FRPP). Such a structural change leads not only to a red-shift of the absorption maxima but strongly enhances their molar extinction coefficients compared to the commercial phototinitiators such as benzophenone (BP) and 4,4 ‘-bis(diethylamino) benzophenone (EMK). In addition, excellent melting points and thermal decomposition temperatures were achieved for those novel compounds. Further, the photochemical reaction behavior was studied by cyclic voltammograms (CV), photolysis and electron spin resonance (ESR) spectroscopy. Finally, benzophenone derivatives in combination with an amine (TEA, triethylamine) as a co-initiator were prepared and initiated the FRPP of trimethylolpropane trimethacrylate (TMPTMA) using a UV lamp as a light source. When used in stoichiometric amounts, the BPDP-D/TEA had the best double bond conversion efficiency among all the compounds studied, and were even superior to the reference compounds of BP/TEA and EMK/TEA. The results and conclusions could provide the fundamental rules applicable for the structural design of benzophenone derivative-based photoinitiators.

I found the field of Chemistry very interesting. Saw the article Gold(i)-NHC-catalysed synthesis of benzofuransviamigratory cyclization of 2-alkynylaryl ethers published in 2020. Recommanded Product: 104-21-2, Reprint Addresses Muchalski, H (corresponding author), Calif State Univ Fresno, 2555 E San Ramon Ave M-S SB70, Fresno, CA 93740 USA.. The CAS is 104-21-2. Through research, I have a further understanding and discovery of 4-Methoxybenzyl acetate

Homogeneous cationic gold(i) catalysis emerged as a preferred avenue for the activation of alkenes and alkynes towards reactions with weak nucleophiles, especially in cyclization reactions. Here we report an intramolecular carboalkoxylation reaction of electron-rich benzyl ethers of 2-ethynylaryl phenols catalysed by a digold(i)-NHC complex. The reaction proceeds efficiently with low catalyst loading and the resulting 2,3-disubstituted benzofurans form in moderate to good yields. Based on the results of a cross-over experiment, spectroscopic data, and DFT calculations, we propose a mechanism that accounts for the observed chemo- and regioselectivity.

Product Details of 119-61-9. Authors Juneau, A; Frenette, M in AMER CHEMICAL SOC published article about in [Juneau, Antoine; Frenette, Mathieu] Univ Quebec Montreal, Dept Chim, Montreal, PQ H3C 3P8, Canada in 2021.0, Cited 21.0. The Name is Benzophenone. Through research, I have a further understanding and discovery of 119-61-9

We report detailed Rainan spectra for the neutral and radical anion forms of benzophenone, fluorenone, 2,2′-bipyridyl, 4,4′-di-tert-butyl-2,2′-dipyridyl, and anthracene. Density functional theory (DFT) predictions for the Raman spectra of these molecules give additional insight into the assignment of each vibrational mode. While the use of DFT has been problematic in quantifying the thermochemistry of highly delocalized radicals, we find that DFT-predicted spectra using the popular B3LYP functional are in excellent agreement with the observed Raman spectra. In the case of the two bipyridyl compounds, the Raman spectra allowed us to conclude that the cis form of the radical anion complexed to a sodium cation was the preferred configuration. Benzophenone and fluorenone radical anions gave a significantly weakened C=O bond stretching vibrational frequency as expected from the population of an antibonding pi* orbital. For benzophenone, the C=O vibration dropped from 1659 to 1403 cm(-1) upon reduction. Similarly, fluorenone showed a C=O vibration observed at 1719 cm(-1) for the neutral form that decreased to 1522 cm(-1) for the radical anion. The structurally rigid anthracene showed relatively smaller Raman band shifts upon single-electron reduction as the pi* orbital is more equally delocalized on the entire structure. In total, we correlated 65 DFT-predicted vibrational modes for the neutral molecules with an overall error of 7.1 cm(-1) (root-mean-square errors (RMSEs)) and 67 DFT-predicted vibrational modes for radical anions with an overall error of 9.9 cm(-1). These comparisons between theory and experiment are another example to demonstrate the power of DFT in predicting the identity and geometry of molecules using Raman spectroscopy.

Lymphomas (cancers of the lymphatic system) account for 12% of malignant diseases worldwide. Burkitt’s lymphoma (BL) is a rare form of non-Hodgkin’s lymphoma in which the cancer starts in the immune B-cells. We report the synthesis and preliminary studies on the antiproliferative activity of a library of 9,10-dihydro-9,10-ethanoanthracene based compounds structurally related to the antidepressant drug maprotiline against BL cell lines MUTU-1 and DG-75. Structural modifications were achieved by Diels-Alder reaction of the core 9-(2-nitrovinyl)anthracene with number of dienophiles including maleic anhydride, maleimides, acrylonitrile and benzyne. The antiproliferative activity of these compounds was evaluated in BL cell lines EBV- MUTU-1 and EBV+ DG-75 (chemoresistant). The most potent compounds 13j, 15, 16a, 16b, 16c, 16d and 19a displayed IC50 values in the range 0.17-0.38 mu M against the BL cell line EBV- MUTU-1 and IC50 values in the range 0.45-0.78 mu M against the chemoresistant BL cell line EBV+ DG-75. Compounds 15, 16b and 16c demonstrated potent ROS dependent apoptotic effects on the BL cell lines which were superior to the control drug taxol and showed minimal cytotoxicity to peripheral blood mononuclear cells (PBMCs). The results suggest that this class of compounds merits further investigation as antiproliferative agents for BL.

Trace chemicals are common in marine and freshwater ecosystems globally. It is recognized that in the environment, individual chemicals are rarely found in isolation. Insufficient work has examined which chemicals co-occur and which methods best identify these mixtures. Using an existing data set, we found evidence that simple correlation analysis is better at identifying mixtures of commonly co-occurring trace chemicals than more commonly used PCA methods. Moreover, simple correlation analysis, unlike PCA, can be used in cases with unbalanced designs and with data points below reportable limits. Application of this approach allowed identification of 10 groups of chemicals commonly found together in freshwaters of the continental US, representing common chemical syndromes. Better identification of co-occurring chemical combinations could aid in our understanding of biological and ecological effects of aquatic contaminants. This research provides evidence of correlation analyses as a more effective method for identifying commonly co-occurring aquatic contaminants. We also examined the patterns of these mixtures with a dataset consisting of concentrations of 406 trace chemicals from 38 sample locations across the continental US. (C) 2020 Elsevier Ltd.

Background. International studies prove the high burden of mental illnesses among refugees. Postmigration stressors in the country of refugemay affect themental health and result in depression. Objectives. The study examines whether postmigration stressors are associated with the prevalence of depressive symptoms among adult refugees in Germany. Methods. Secondary data analysis based on cross-sectional data of the IAB-BAMF-SOEP Survey of Refugees 2016 (N= 4465) that is representative for Germany. Depressive symptoms were measured using the Patient Health Questionnaire-2 (PHQ-2). Unadjusted and adjusted odds ratios (ORs) and confidence intervals (CIs) were calculated with binary logistic regression models to examine associations between depression and sociodemographic, postmigration, and psychosocial factors. Results. Depressive symptoms show 19.4% of the surveyed refugees. Almost all selected postmigration stressors are significantly associated with depression after adjustment for sociodemographic and psychosocial factors. Unemployment (aOR= 1.48 [1.04-2.12]), loneliness (aOR= 1.14 [1.10-1.18]), and a rejected or undecided asylum application (aOR= 1.34 [1.06-1.70]) increase the odds of depressive symptoms, whereas asylum interviews (aOR= 0.71 [0.56-0.91]) and higher housing satisfaction (aOR= 0.94 [0.91-0.98]) lower the odds of depression. Conclusions. Postmigration stress is associated with the occurrence of depressive symptoms. Sociopolitical interventions considering stressful and protective factors of the postmigration phase can reduce the burden of mental disorders in refugee populations.

We present a detailed DFT mechanistic study on the first Ni-catalyzed direct carbonyl-Heck coupling of aryl triflates and aldehydes to afford ketones. The precatalyst Ni(COD)(2) is activated with the phosphine (phos) ligand, followed by coordination of the substrate PhOTf, to form [Ni(phos)(PhOTf)] for intramolecular PhOTf to Ni(0) oxidative addition. The ensuing phenyl-Ni(ii) triflate complex substitutes benzaldehyde for triflate by an interchange mechanism, leaving the triflate anion in the second coordination sphere held by Coulomb attraction. The Ni(ii) complex cation undergoes benzaldehyde C=O insertion into the Ni-Ph bond, followed by beta-hydride elimination, to produce Ni(ii)-bound benzophenone, which is released by interchange with triflate. The resulting neutral Ni(ii) hydride complex leads to regeneration of the active catalyst following base-mediated deprotonation/reduction. The benzaldehyde C=O insertion is the rate-determining step. The triflate anion, while remaining in the second sphere, engages in electrostatic interactions with the first sphere, thereby stabilizing the intermediate/transition state and enabling the desired reactivity. This is the first time that such second-sphere interaction and its impact on cross-coupling reactivity has been elucidated. The new insights gained from this study can help better understand and improve Heck-type reactions.

A unique deoxygenative cyclodimerization of alkynyl 1,2-diketones facilitated by Ti((OPr)-Pr-i) (4) is achieved, affording a series of highly functionalized furan products. An unusual C-C bond and C=O bond cleavage of the substrates is observed, and Ti(OiPr)(4) plays triplicate roles in the reaction. Furthermore, the products show uncommon fluorescent emission in the solid state, indicating the potential practical applications of this work.

A series of synthetically accessible ligands based on new 2-(R-sulfonamido)benzamide have been prepared (R = methyl for H3M; R = 4-toly for H3T and T2CN; R = 2,4,6-triisopropylphenyl for H(3)iP and HiPCN). The R-substituents were selected to vary in sizes. Allowing ligand H(3)iP and palladium acetate to stand in solvent leads to self-assembly of the well-defined solvent- and stoichiometry-controlled tetranuclear or hexanuclear coordination macromolecules Pd-4(iP)(2) and (PdHiP)(6), which were analysed by X-ray crystallography. It was observed that palladium active species for Suzuki coupling catalysis could be stabilized by these simple and synthetically assessable N-donor ligands as revealed by turnover frequencies reaching 5500h(-1). Electronic features of these N-donors appear to be more important than the steric properties. (C) 2019 Elsevier B.V. All rights reserved.
