A copper and silver-promoted intermolecular 1,2-alkylarylation of styrenes with alpha-carbonyl alkyl bromides and arenes for producing highly bulky 1,1-diarylalkane derivatives has been developed. In this transformations, two new C-C bonds were formed in a single reaction step through C-Br bond cleavage and C(sp(2))-H functionalization. This protocol tolerates a variety of alpha-carbonyl alkyl bromides, including primary, secondary and tertiary alpha-bromoalkyl ketone esters.

Traditional cross-coupling reactions show some disadvantages like the use of organohalides or the production of stoichiometric amounts of waste. The dehydrative homo- or heterocoupling of alcohols therefore arises as an interesting approach for a highly atom-economical formation of carbon-carbon bonds, since water is produced as the only by-product. We herein report a simple and direct, metal-free protocol for the synthesis of olefins by applying catalytic amounts of a sulfonic acid and triphenylphosphane under air. A variety of olefins could be synthesized from benzylic alcohols under relatively mild conditions. Additionally, dehydrative hydroarylation of benzylic alcohols with electron-rich arenes was possible by using only Bronsted acid under otherwise same reaction conditions. We could show that phosphane additives are essential to overcome oligomerization as main side reaction by the occupancy of the reactive carbocation intermediate.

Photoexcited electron-hole pairs on a semiconductor surface can engage in redox reactions with two different substrates. Similar to conventional electrosynthesis, the primary redox intermediates afford only separate oxidized and reduced products or, more rarely, combine to one addition product. Here, we report that a stable organic semiconductor material, mesoporous graphitic carbon nitride (mpg-CN), can act as a visible-light photoredox catalyst to orchestrate oxidative and reductive interfacial electron transfers to two different substrates in a two-or three-component system for direct twofold carbon-hydrogen functionalization of arenes and heteroarenes. The mpg-CN catalyst tolerates reactive radicals and strong nucleophiles, is straightforwardly recoverable by simple centrifugation of reaction mixtures, and is reusable for at least four catalytic transformations with conserved activity.

Formula: C7H4F2O2. I found the field of Chemistry; Science & Technology – Other Topics; Engineering very interesting. Saw the article Mechanochemical Synthesis of Amides with Uronium-Based Coupling Reagents: A Method for Hexa-amidation of Biotin[6]uril published in 2020, Reprint Addresses Kananovich, DG; Aav, R (corresponding author), Tallinn Univ Technol, Sch Sci, Dept Chem & Biotechnol, EE-12618 Tallinn, Estonia.. The CAS is 385-00-2. Through research, I have a further understanding and discovery of 2,6-Difluorobenzoic acid.

Solvent-free, atom-efficient, and mechanochemically activated reactions have emerged as synthetic strategy for sustainable chemistry. Herein we report a new mechanochemical approach for the amide coupling of carboxylic acids and amines, mediated by combination of (1-cyano-2-ethoxy-2-oxoethylidenaminooxy)-dimethylaminomorpholinocarbenium hexafluorophosphate (COMU) or N,N,N’,N’-tetramethylchloroformamidinium hexa-fluorophosphate (TCFH) and K2HPO4. The method delivers a range of amides in high yields (70-96%) and fast reaction rates. The reaction protocol is mild, keeps stereochemical integrity of the adjacent to carbonyl stereocenters, and streamlines isolation procedure for solid amide products. Minimal waste is generated due to the absence of bulk solvent. We show that K2HPO4 plays a dual role, acting as a base and a precursor of reactive acyl phosphate species. Amide bonds from hindered carboxylic acids and low-nucleophilic amines can be assembled within 90 minutes by using TCFH in combination with K2HPO4 or N-methylimidazole. The developed mechanochemical liquid-assisted amidation protocols were successfully applied to the challenging couplings of all six carboxylate functions of biotin[6]uril macrocycle with phenylalanine methyl ester, resulting in 80% yield of highly pure hexa-amide-biotin[6]uril. In addition, fast and high-yielding synthesis of peptides and versatile amide compounds can be performed in a safe and environmentally benign manner, as verified by green metrics.

Quantitative structure-activity relationship models are used in toxicology to predict the effects of organic compounds on aquatic organisms. Common filter feature selection methods use correlation statistics to rank features, but this approach considers only the correlation between a single feature and the response variable and does not take into account feature redundancy. Although the minimal redundancy maximal relevance approach considers the redundancy among features, direct removal of the redundant features may result in loss of prediction accuracy, and cross-validation of training sets to select an optimal subset of features is time-consuming. In this paper, we describe the development of a feature selection method, Chi-MIC-share, which can terminate feature selection automatically and is based on an improved maximal information coefficient and a redundant allocation strategy. We validated Chi-MIC-share using three environmental toxicology datasets and a support vector regression model. The results show that Chi-MIC-share is more accurate than other feature selection methods. We also performed a significance test on the model and analyzed the single-factor effects of the reserved descriptors.

An expedient and eco-friendly synthesis of 1-aryl/heteroaryl-[1,2,4]-triazolo[4,3-a]quinoxalin-4(5H)-ones (4) has been accomplished via iodobenzene diacetate mediated oxidative intramolecular cyclization of 3-(2-(aryl/heteroarylidene)hydrazinyl)-quinoxalin-2(1H)-ones (3). Ten synthesized compounds 3 and 4 (10-40 mu g) on irradiation with UV light at lambda(max) 312 nm could lead to cleavage of supercoiled pMaxGFP DNA (Form I) into the relaxed DNA (Form II) without any additive. Further, DNA cleaving ability of triazoles was quantitatively evaluated and was found to be dependent on its structure, concentration, and strictly on photoirradiation time. Mechanistic investigations using several additives as potential inhibitors/activator revealed that the DNA photocleavage reaction involves Type-I pathway leading to formation of superoxide anion radicals (O-2(-center dot)) as the major reactive oxygen species responsible for photocleavage process.

A series of substituted benzoate-bridged dichromium(II, II) complexes [Cr-2(RCO2)(4)(THF)(2)] ([Cr-2]), where RCO2- is substituted benzoate, was synthesized and its structural and magnetic properties were investigated. The orbital energies, as well as magnetic coupling energies, were also investigated using computational approaches. The HOMO/LUMO energy levels of the complexes are strongly dependent on the acidity, i.e., pK(a), of the corresponding benzoic acids (RCO2H), revealing a linear trend in the respective groups of non-ortho, mono-ortho, and bi-ortho substituted groups. The Cr center dot center dot center dot Cr magnetic coupling constant (E-S (T)) is little affected by pK(a); instead, the E-S (T) is associated with the HOMO/LUMO gap and strongly correlated with the Cr center dot center dot center dot Cr distance.
