The development of carbonaceous materials as metal-free catalysts integrating different types of catalysis in a single system represents a significant advance in cascade/tandem organic synthesis. Zero-dimensional carbon dots with tuneable optical properties and easily modifiable surface functionalities can be harnessed as a carbocatalyst for merging photooxidation and acid-catalyzed reactions in one pot. Herein, we explore carbon dots decorated with hydrogen sulfate groups as a photocatalyst for the dehydrogenative cross-coupling of xanthenes with ketones, arenes and 1,3-dicarbonyl compounds that showed high efficiency and selectivity under visible-light irradiation. The sulphated carbon dots demonstrate dual catalytic properties, wherein they induced the rapid photooxidation of xanthenes in the presence of molecular oxygen to form a hydroperoxy intermediate followed by coupling of nucleophiles catalysed by the acidic surface functional groups. The methodology represents an operationally simple pathway for the generation of C-C coupling products in a short reaction time with wide substrate scopes under mild conditions. The catalyst is easily separable and can be reused over multiple cycles with good efficiency.

Well-defined ruthenium(II) biscarboxylate complexes enabled selective ortho-deuteration with weakly-coordinating, synthetically useful carboxylic acid with outstanding levels of isotopic labeling. The robust nature of the catalytic system was reflected by a broad functional group tolerance in an operationally-simple manner, allowing the isotope labeling of challenging pharmaceuticals and bioactive heterocyclic motifs. The synthetic power of our method was highlighted by the selective tritium-labeling of repaglinide, an antidiabetic drug, providing access to defined tritium labeled therapeutics.

A trifluoroacetic-acid-mediated desulfurilative sulfonylthiolation of arenes using SS-morpholino dithiosulfonate is described. This system is based on selective activation of the morpholino group over the tosyl group of the doubly transformable sulfur surrogate. Mechanistic studies suggested that the reaction proceeds through electrophilic aromatic substitution followed by sulfur extrusion. The wide substrate scope of this reaction and the transformability of the resulting thiosulfonates enable expeditious access to divergent multifunctionalized sulfides.

Dusel, SJS; Konig, B in [Duesel, Simon Josef Siegfried; Koenig, Burkhard] Univ Regensburg, Inst Organ Chem, Univ Str 31, D-93053 Regensburg, Germany published Oxidative Photochlorination of Electron-Rich Arenes via in situ Bromination in 2020, Cited 41.

Electron-rich arenes are oxidatively photochlorinated in the presence of catalytic amounts of bromide ions, visible light, and 4CzIPN as organic photoredox catalyst. The substrates are brominated in situ in a first photoredox-catalyzed oxidation step, followed by a photocatalyzed ipso-chlorination, yielding the target compounds in high ortho/para regioselectivity. Dioxygen serves as a green and convenient terminal oxidant. The use of aqueous hydrochloric acid as the chloride source reduces the amount of saline by-products.

In this study, two new copper (II) carboxylate complexes, [Cu(4-mba)(2) (tmeda)](1) and [Cu(3mba)(2)(H2O)(2)(tmeda)](2) (4-mbaH = 4-methylbenzoic acid, 3-mbaH = 3-methylbenzoic acid, tmeda = N,N,N’,N’-tetramethylethyleneamine) were synthesized. The structures and properties of the complexes were determined by X-ray single crystal diffraction method and FT-IR spectroscopy. While the crystal packing of the complex 1 is stabilized by C-H center dot center dot center dot O hydrogen bonds, in the complex 2, the molecules are connected to each other by C-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds. The optimized structures were formed using density functional theory (DFT) at the B3LYP level within the 6-311G(d,p) and LAN2DZ basis sets.

Mitochondrial complex III is one of the most promising targets for a number of pharmaceuticals and fungicides. Due to the wide-spread use of complex III-inhibiting fungicides, a considerable increase of resistance has occurred worldwide. Therefore, inhibitors with novel scaffolds and potent activity against complex III are still in great demand. In this article, a new series of amide compounds bearing the diaryl ether scaffold were designed and prepared, followed by the biological evaluation. Gratifyingly, several compounds demonstrated potent activity against succinate-cytochrome c reductase (SCR, a mixture of mitochondrial complex II and complex III), with compound 3w possessing the best inhibitory activity (IC50 = 0.91 +/- 0.09 mu mol/L). Additional studies verified that 3w was a new inhibitor of complex III. Moreover, computational simulations elucidated that 3w should bind to the Q(o) site of complex III. We believe this work will be valuable for the preparation and discovery of more complex III inhibitors.

The first oxidative coupling of alkylnitriles with aromatic carboxylic acids using di-tert-butyl peroxide (DTBP) as oxidant was achieved under the catalysis of ionic Fe(III) complexes bearing an imidazolinium cation. This protocol features nontoxic iron catalysis, direct alpha-C(sp(3))-H bond oxidative esterification of alkylnitriles, non-prefunctionalized starting materials, and a broad substrate scope with outstanding steric hindrance tolerance, providing a novel, straightforward, and green approach toward cyanomethyl ester synthesis.

Equations for vapor pressure VP, as log VP, at 298.15 K for a set of 1016 liquid organic and organometallic compounds have been constructed using Abraham descriptors. The regression standard deviations of 0.28 and 0.31 log units are excellent by comparison with literature values for large data sets. Similar equations for a set of 359 solid organic and organometallic compounds were very poor, but if carboxylic acids were excluded we obtained equations for 261 compounds with standard deviations of 0.62 and 0.66 log units. For the 98 carboxylic acids taken separately we obtained equations with standard deviations of 0.84 and 0.91 log units. Equations for the carboxylic acids were substantially different to those that excluded carboxylic acids, due, we suggest, to the particular dimeric structure of the crystalline carboxylic acids.
